Hearing Impairments

Fact Sheet

What is a hearing impairment?

Having a hearing impairment means that a child has lost some hearing in one or both ears. Hearing impairments are described according to how much hearing has been lost. Loss is usually explained as mild, moderate, moderate to severe, severe, or profound.

How is it manifested?

There are different types of hearing loss: conductive, sensory, mixed (conductive and sensory combined), and neural.

  1. Conductive hearing loss
    This happens when there is a problem with part of the outer or middle ear. Most children with conductive hearing loss have a mild hearing loss and it is usually temporary. In most cases, medical treatment helps.
  2. Sensory hearing loss
    This happens when the cochlea (the snail-shaped structure in the inner ear containing the organ of hearing) is not working correctly because the tiny hair cells are damaged or destroyed. Depending on the loss, a child may be able to hear most sounds (although they would be muffled), only some sounds, or no sounds at all. Sensory hearing impairment is almost always permanent and a child’s ability to talk normally may be affected.
  3. Neural hearing loss
    This occurs when there is a problem with the connection from the cochlea to the brain. Neural hearing loss means the nerve that carries the messages from the cochlea to the brain is damaged.
  4. Mild impairment
    The child hears and can understand a normal conversational voice, but will not follow all quiet speech that others can hear and may often ask, “What?”
  5. Moderate impairment
    The child does not hear all of normal conversational speech and requires louder, stronger, and aggressively-toned responses. Some effect on the child’s speech development is likely unless the child receives help.
  6. Severe impairment
    The child will not hear any normal conversation and only a few sounds of loud speech.
  7. Profound impairment:
    The child will hear only the loudest noises and may not get sufficient help even from a hearing aid. Insertion of a cochlear implant (“bionic ear”) may need to be considered.

Who is affected?

Approximately 40 in 10,000 children are born with a hearing loss. An additional 12 in 10,000 will acquire at least a moderate hearing loss by the age of seventeen.

How is it diagnosed or detected?

The type of tests used to diagnose hearing loss depend on the age of the child, but can include:

  • Simple tests, such as shaking a rattle nearby and observing the response (behavioural observation audiometry).
  • Tests such as auditory brainstem response testing, which measure the electrical activity in the brain in response to a sound.
  • Tests with an audiometer – a machine that produces sounds such as beeps and whistles. Whether or not the child can hear certain sounds helps to pinpoint his/her degree of hearing loss.

Getting The Most Out of Team Meetings

Parent and teacher meeting

Over time, as a parent, you may come across a wide range of professionals involved with your child. You may first be involved with people from the medical field, staff from an early intervention program, and eventually school board personnel. It is beneficial to develop positive relationships with the team of professionals supporting you and your child. Regular communication will be needed to:

  • share and update information about your child
  • problem solve (any barriers or obstacles)
  • develop common goals and strategies that can be implemented in your child’s program at school, child care, and at home
  • share successes and progress
  • develop a trust with others working with your child over a long period of time

Preparing for a meeting

Formal and informal meetings with your child’s team will take place for various reasons (e.g., set goals, review programming and strategies). Understanding the purpose of each meeting will help you as the parent and primary decision maker for your child to develop and strengthen your role and relationship with other team members.

At times, it may seem frustrating to answer questions that you have addressed in the past with other professionals. With a little preparation, meetings can be a positive way of sharing critical information about your child. Ask the following questions of the person or primary contact who is organizing the meeting:

  1. What is the purpose of the meeting?
    Meetings may have different purposes. The first time you meet with professionals may be for information sharing only, or may include goal setting and program planning for your child. As your relationship with the team develops, you may continue to meet on a regular basis to review your child’s programming, or to address any new issues.
  2. Who will be at the meeting?
    Ask who will be attending the meeting, the agency they are from and their specific role with your child. If you are unfamiliar with a person from another agency ask for a pamphlet or written information about the agency before the meeting.
  3. What do you need to bring to the meeting?
    During the meeting you may be asked questions about your child and general information about any other services your child is receiving. You can choose to share reports or any documents that you feel will benefit your child during this meeting. These reports may include previous assessment reports and programming notes. It is a good idea to organize your reports and documents in one place, such as a binder. Information can be filed as it is collected and organized for easy access as it is needed.

    The Child Information Binder can help you create a binder or booklet that contains your child’s photograph, information specific to your child’s strengths, interests and needs, and a list of professionals involved with your child. Check out the For More Information box at the end of this document for details.

    Remember that reports and information about your child can only be shared with your agreement. Make sure that you understand why the information is needed and who will be able to see the information. You may be asked for your permission to share information, or to sign a “Consent to Release Information” form.

Tips for a successful meeting

Now that you are prepared for the meeting there are a few things you can do during the meeting to make it successful.

  1. Bring a supportive person with you
    Bring a person with whom you are comfortable to the meeting. It is important that you have someone with you who shares your vision and can help you advocate for other supports you would like for your child. This person may be a professional who is part of the team, a relative, or a friend. Make sure you discuss and agree upon their role before attending the meeting.
  2. Take meeting notes
    It is good to write notes about each meeting. At many meetings, someone will be the designated note-taker. Request a copy of the meeting notes or “minutes”, but keep your own written record as well, just in case.

    In your notes you should include:

    • who attends each meeting
    • what was discussed
    • what decisions were made
    • the actions resulting from the meeting (e.g., changes to programming, requesting services, contacting other professionals)
    • who is responsible for these actions
    • the time frame needed for each action
    • the date of the next meeting

    This will help you remember who is going to do what and when. The Meeting Notes sheet found at the end of this document can help you organize your notes.

  3. Communicate for success
    Building a strong, supportive team can be a challenging task. The benefits of maintaining positive communication with team members, however, can enhance your child’s experience in a program and help to plan for the future. You may not always agree with what professionals suggest or recommend for your child. Even if you don’t agree, the following suggestions may help you build a positive working relationship:

    • Always start and end on a positive note (e.g., saying something good that has taken place in your child’s life, or is now happening). The beginning of a meeting is an excellent time to show your child’s picture to the team members.
    • Give your full attention to each person while they are talking.
    • If you are unsure about any comments during the meeting, ask the person to clarify and provide examples of what they are saying.
    • Make sure you have had an opportunity to share information about your child. You can give suggestions or ideas about things that motivate your child, or activities you do at home. Remember that you are the expert when it comes to your child and the team will value your insight.

If you are feeling overwhelmed at any point during a meeting, you can request that the meeting be stopped for a short period. Do not feel pressured into making decisions on the spot when you really need time to think about them. Tell your team members that you would like to take a few days to think over their input before making a final decision regarding your child’s care or schooling.

Solving Problems

Despite your best efforts, there may be differences of opinion. You will need to work together to find solutions. Try the following steps:

  1. Define the problem/concern
    Share your concerns. If you feel that a decision or outcome of a meeting is not in your child’s best interests, then tell your team. You may be more comfortable with one member of the team and feel confident to talk to her about your concerns. That person is responsible for sharing your concerns with the full team and looking for solutions. Write down any points of discussion that you do not agree with or would like changed. Give a copy of your concerns to the team. It will provide the team members with a clear understanding of your viewpoint and help to develop a plan of action to move forward.
  2. Choose the solutions that almost everyone can accept
    Evaluate all possible solutions and select realistic options. There is no point in looking at solutions that you know will not occur for another 6-12 months. Record who is responsible for what action and establish a timeline of when they will get back to you.
  3. Follow-up and evaluation
    Set a date for a follow-up meeting. At that meeting you will be able to discuss if the solution is working and if further changes are needed. Choose another option if necessary.

The best relationships are built on mutual respect, trust, and openness, where both parents and professionals exchange information and ideas about the best care, medical intervention, or educational program for your child.

Fragile X

Fact Sheet

What is Fragile X?

Fragile X is a hereditary/genetic condition that can impact families in many ways. It includes Fragile X Syndrome (FXS), the most common cause of genetically-inherited cognitive impairment ranging from subtle learning disabilities and a normal IQ, to severe cognitive or intellectual challenges including autism or “autistic like” behaviour. Symptoms often include unique physical characteristics, behavioural deficits, and delays in speech and language development.

Fragile X also includes Fragile X-associated Tremor Ataxia Syndrome (FXTAS), a balance, tremor and memory condition that affects some older male carriers of the permutation. Fragile X can also include problems for female carriers such as early menopause, medically referred to as premature ovarian failure (POF).

How is it manifested?

Fragile X is the result of a genetic variation in the X chromosome. Specifically, there is a full mutation on one end of the FMR1 gene. This gene contains information about how to make the protein FMRP. Individuals with Fragile X do not make this protein, because the FMR1 gene is not expressed, due to its being replicated more than 200 times. Males with a full mutation experience severe symptoms of Fragile X. Females with a full mutation will show some symptoms of Fragile X, but will generally not be affected as severely. This gender difference is particularly evident in terms of intellectual impairment, but is less obvious in terms of behaviour and emotional difficulties.

Some individuals have a permutation of the gene, between 55 to 200 repeats, and show few, or no, symptoms of Fragile X.

Other people are carriers of Fragile X, but do not show any symptoms. In these cases, the FMR1 gene is replicated 45 to 55 times. A man who is a carrier will pass the permutation onto all female children. Male children, however, will not be affected. A woman who is a carrier has a 50% chance of passing the permutated gene onto each child, male or female.

Fragile X can be passed down a family line through carriers or permutation for generations before symptoms actually appear in a child.

Common characteristics of Fragile X include

  • long face, large ears and flat feet
  • hyperextensible joints
  • learning disabilities and intellectual impairment
  • decreased attention span
  • hyperactivity
  • anxiety
  • moodiness
  • seizures (25% of people with Fragile X experience seizure activity)
  • behaviours commonly classified as autistic (difficulty with transitions, repetitive movements, sensitivity to overwhelming environmental stimuli, or self-injurious behaviour)

Who is affected?

Fragile X is the most common type of inherited developmental disorder in the world. Males are affected more frequently and typically more severely than females. Recent estimates indicate that for males with the full mutation the incidence rate is 1 in 4,000. For females with the full mutation, the incidence rate is 1 in 8,000.

How is it diagnosed or detected?

A simple genetic test or DNA analysis can determine the presence of the mutated gene responsible for Fragile X. It also provides extremely accurate detection of individuals who are carrying the gene and can be performed before birth. This type of test is sufficient if testing specifically for Fragile X Syndrome. However, in cases where there is no history of Fragile X and the cause of intellectual impairment is unknown, a comprehensive genetic evaluation should be performed.

Due to the fact that Fragile X can vary greatly among individuals in terms of symptoms and severity, to the point of being very subtle in some females, most individuals with Fragile X are not correctly diagnosed.

Fetal Alcohol Spectrum Disorder

Fact Sheet

What is Fetal Alcohol Spectrum Disorder?

Fetal Alcohol Spectrum Disorder, or FASD, is an umbrella term used to describe the range of permanent disabilities caused by prenatal exposure to alcohol. Prenatal exposure to alcohol is a leading cause of preventable birth defects. Alcohol can interfere with the growth and development of the fetal body systems, especially the central nervous system (the brain and spinal cord). Although it can vary from mild to severe the effects can include physical, mental, behavioural, and/or learning disabilities with possible lifelong implications. It is one of the top three known causes of developmental delay in children in Canada along with Spina Bifida and Down Syndrome. The greatest risks of FASD are associated with high levels of drinking, including binge drinking, or heavy drinking. Right now, there is no way of knowing how much alcohol is safe to drink during pregnancy. Less is better. None is best. FASD is a life-long condition.

There are four terms commonly used to describe FASD:

Fetal Alcohol Syndrome(FAS): most severe and visibly identifiable form of FASD. FAS is characterized as: growth deficiency; a unique cluster of minor facial abnormalities; severe CNS abnormalities; and prenatal alcohol exposure.

Partial Fetal Alcohol Syndrome (pFAS): a diagnostic classification for patients who present most but not all the growth deficiency and/facial features of FAS; severe SNS abnormalities; and prenatal alcohol exposure.

Alcohol Related Birth Defects(ARBD): patients with ARBD have problems with how some of their organs were formed and function including: heart, kidney, bones, hearing, and vision.

Alcohol-Related Neurodevelopmental Disorder (ARND): patients with ARND have issues with their brain and nervous system formation and functionality. There are no facial abnormalities or growth deficiencies.
Neurobehavioural Disorder associated with Prenatal Alcohol Exposure (ND-PAE): patients with ND-PAE have problems with thinking, behaviour, and life skills. This is due to alcohol exposure during pregnancy.

How is it manifested?

Although there is great variability in the characteristics of children with FASD, three common traits include:

Growth Pattern

  • slowed growth
  • small birth weight and head circumference
  • small in stature

Distinct facial features

  • thin upper lip
  • smooth philtrum (groove between upper lip and nose)
  • small eye openings
  • flat mid-face

Central nervous system deficits

  • learning disabilities
  • developmental delays
  • inappropriate social skills
  • difficulty learning from consequences
  • hyperactivity
  • poor concentration
  • memory problems
  • difficulty following instructions

Children may have problems in all three areas, or just one, depending on how they are affected. Often children will have normal growth and facial features, but display central nervous system deficits.

Who is affected?

The exact number of children born with FASD is unknown. FASD affects approximately 1% of people living in Canada and it is believed to be 5 out of every 100 live births worldwide.

How is it diagnosed or detected?

The criteria for the diagnosis of FASD are based on the presence of the following

  • evidence of excessive maternal drinking during pregnancy
  • characteristic facial dysmorphology (e.g., microcephaly, poorly-developed philtrum, thin upper lip and flattened maxillary area)
  • pre- and/or postnatal growth delays (weight, length and/or height below the 10th percentile
  • central nervous system (CNS) damage (e.g., signs of neurological abnormality, developmental delay, intellectual impairment, or neurobehavioural anomalies).

Failure to Thrive

Fact Sheet

What Is Failure to Thrive?

Although it has been recognized for more than a century, Failure to Thrive Syndrome (FTT) lacks a precise definition. This is partly because it describes a condition rather than a specific disease. Children who fail to thrive do not receive, or are unable to take in, retain, or utilize the calories needed to gain weight and grow as expected.

Most diagnoses of Failure to Thrive Syndrome are made in infants and toddlers in the first few years of life (a crucial period of physical and mental development). After birth, a child’s brain grows as much in the first year as it will grow during the rest of the child’s life.

How is it manifested?

A child who has stopped growing and/or has experienced significant weight loss may be suffering from Failure to Thrive Syndrome. A medical assessment is necessary to determine whether the syndrome is a medical or a non-medical condition.

The following characteristics are often present in failure-to-thrive children.

  • lack of appropriate weight gain
  • irritability
  • easily fatigued
  • excessive sleepiness
  • lack of age-appropriate social response
  • does not make vocal sounds
  • delayed motor development
  • learning and behaviour difficulties later in childhood

Potential Causes

  • not enough food offered
  • child eats too little due to prematurity, developmental delays, or has sensitivity to textures and tastes
  • health problems involving the digestive system, such as gastroesophageal reflux (GER), chronic diarrhea, Cystic Fibrosis, chronic liver disease, and Celiac Disease
  • food intolerance –body is sensitive to certain foods
  • an ongoing illness or disorder
  • infections
  • metabolic disorders

Who is affected?

An accurate number of incidences of Failure to Thrive Syndrome is unknown and often depends on the population. However, approximately 5-10% of low birth weight children and children living in poverty have FTT.

How is it diagnosed or detected?

Due to the fact that children grow and develop at different rates, it is necessary for a paediatrician to keep track of a child’s growth and weight during regular checkups. In making the diagnosis, it is necessary to provide the physician with a detailed history of the child combined with a current physical examination. This includes: diet and feeding behaviours; medical history; past and current medications; social history; and family history. Growth charts for length, weight, and head circumference help in confirming the diagnosis of Failure to Thrive Syndrome..

Down Syndrome

Fact Sheet

What is Down Syndrome?

Down Syndrome is a genetic condition resulting from an extra 21st chromosome which often causes delays in physical and intellectual development. It occurs in approximately 1 in every 800 live births. Individuals with Down Syndrome have 47 chromosomes instead of the usual 46.

Three genetic variations can cause Down Syndrome. Approximately 92% of the time, Down Syndrome is caused by the presence of an extra Chromosome 21 in all cells of the individual. In such cases, the extra chromosome originates in the development of either the egg or the sperm. Consequently, when the egg and sperm unite to form the fertilized egg, three, rather than two, Chromosome 21’s are present. As the embryo develops, the extra chromosome is repeated in every cell. This condition, in which three copies of Chromosome 21 are present in all cells of the individual, is called Trisomy 21.

In approximately 2-4% of cases, Down Syndrome is due to Mosaicism. This situation is similar to Trisomy 21 but, in this instance, the extra Chromosome 21 is present in some, but not all, cells of the individual. For example, the fertilized egg may have the right number of chromosomes, but, due to an error in chromosome division early in embryonic development, some cells acquire an extra Chromosome 21. Thus, an individual with Down Syndrome due to Mosaic Trisomy 21 will typically have 46 chromosomes in some cells, but will have 47 chromosomes (including an extra Chromosome 21) in others. In this situation, the range of the physical problems may vary, depending on the proportion of cells that carry the additional Chromosome 21.

The third genetic variation is called Translocation. This refers to the type of Down Syndrome that is caused by rearranged chromosome material. There are three 21 chromosomes, similar to Trisomy 21 but in this case, one of the 21st chromosomes has attached to another chromosome instead of being separate. Only 3-4% of babies born with Down Syndrome will have Translocation.

How is it manifested?

  • muscle hypotonia (low muscle tone)
  • flat facial profile (a somewhat depressed nasal bridge and a small nose)
  • oblique palpebral fissures (an upward slant to the eyes)
  • dysplastic ear (an abnormal shape of the ear)
  • a single deep crease across the center of the palm
  • hyperflexibility (an excessive ability to extend the joints)
  • epicanthal folds (small skin folds on the inner corner of the eyes)
  • excessive space between large and second toe
  • enlargement of tongue in relationship to size of mouth

Who is affected?

It is estimated that 1 in every 800-1,000 children born in Canada are diagnosed with Down Syndrome. It is the most frequently-occurring chromosomal abnormality.

How is it diagnosed or detected?

Down Syndrome is usually identified at birth or shortly thereafter. Initially, the diagnosis is based on physical characteristics that are commonly seen in babies with Down Syndrome. These include low muscle tone, a single crease across the palm of the hand, a slightly flattened facial profile, and an upward slant to the eyes. The diagnosis must be confirmed by a chromosome study (karyotype). A karyotype provides a visual display of the chromosomes grouped by their size, number, and shape. Chromosomes may be studied by examining blood or tissue cells.

There are also two types of prenatal tests used to detect Down Syndrome in a fetus: screening and diagnostic tests. The screening test estimates the risk that a fetus has Down Syndrome while a diagnostic test determines whether or not the fetus has a condition with an accuracy of 99%. However, diagnostic tests are more invasive since it is tested in utero. Contact your health care provider for more information.

Developmental Delay

Fact Sheet

What is a Developmental Delay?

Children identified as “developmentally delayed” tend to develop at a slower rate than typical children at the same age level. This may be evident in a single area of development, or in multiple areas. Developmental Delay is a non-categorical label often used by educators and health practitioners who are reluctant to identify preschoolers with a categorical label. Even with typical development, there are age ranges for developmental milestones.

How is it manifested?

Common reasons why a child might be developmentally delayed are

  • premature birth
  • hospitalization immediately or soon after birth
  • insufficient brain cell development
  • damage to brain cells before or during birth (e.g., Cerebral Palsy)

It is not uncommon for a developmental delay to co-exist with another disorder, such as

  • behavioural and emotional disorders – inherent or related to physical, sexual or emotional abuse early in life
  • sensory impairments – vision or hearing problems
  • medical/health conditions – allergies or asthma
  • genetic disorders (e.g., Down Syndrome)
  • Attention Deficit Disorder (ADD)

Who is affected?

Developmental Delay is the most common type of disability among preschool children. It is more common in males than in females. As children move into the school system, many are diagnosed with a more specific disability.

How is it diagnosed or detected?

For typically developing children, a paediatrician should screen for delays in their development during regular examinations. This may consist of simple questions about what a child is able to do, or may include a formal screening test.

Common characteristics, which may be apparent in a child with a developmental delay, include

  • difficulty with change or transition periods
  • difficulty remaining on-task and with task-completion
  • difficulty understanding concepts that are abstract, as opposed to concrete
  • delays in expressive and/or receptive language development
  • problems organizing and/or remembering information
  • difficulty during unstructured activities

Dandy-Walker Syndrome

Fact Sheet

What is Dandy Walker Syndrome?

Dandy-Walker Syndrome (DWS) is a congenital brain malformation involving the cerebellum (an area at the back of the brain that controls movement) and the fluid-filled spaces around it. The key features of this syndrome are an enlargement of the fourth ventricle (a small channel that allows fluid to flow freely between the upper and lower areas of the brain and spinal cord), a partial or complete absence of the cerebellar vermis (the area between the two cerebellar hemispheres), and cyst formation near the internal base of the skull. An increase in the size of the fluid spaces surrounding the brain as well as an increase in pressure may also be present.

Dandy-Walker Syndrome is frequently associated with disorders of other areas of the central nervous system including absence of the corpus callosum (the connecting area between the two cerebral hemispheres), and malformations of the heart, face, limbs, fingers and toes.

How is it manifested?

Symptoms of Dandy-Walker Syndrome often occur in infancy but can also occur in older children. Symptoms may include:

  • Impaired development of normal speech and language
  • Slow motor development
  • Irritability
  • Vomiting
  • Convulsions
  • Unsteadiness
  • Lack of muscle coordination
  • Jerky eye movements
  • Increased head circumference
  • Bulging of the back of the skull
  • Problems with the nerves that control the eyes, face, and neck
  • Abnormal breathing
  • head circumference or progressive enlargement of the skull

Who is affected?

  • The incidence is approximately 1 in 2,500 newborns.
  • DWS occurs more frequently in females than males

Diagnosis:

The majority of individuals with DWS are diagnosed in their first year of life as a result of the commonly associated hydrocephalus. However, a definitive diagnosis can be made by ultrasound, CT-scan, or MRI (allows a detailed evaluation of Dandy-Walker malformation lesions and complications. MRI evaluation can then be used antenatally to confirm the diagnosis and gain more detailed information).

Treatment:

Talk with your child’s doctor about the best treatment plan. Treatment will depend on the problems caused by the syndrome. This may involve placing a special tube called a shunt inside the skull to drain excess fluid to reduce pressure and help control swelling.

Cystic Fibrosis

Fact Sheet

What is Cystic Fibrosis?

Cystic Fibrosis (CF) is the most common, fatal genetic disease affecting young Canadians. CF affects mainly the lungs and the digestive system. In the lungs, CF causes severe breathing problems. A build-up of thick mucus makes it difficult to clear bacteria and leads to cycles of infection and inflammation which damage the delicate lung tissues.

In the digestive tract, CF makes it extremely difficult to digest and absorb adequate nutrients from food. Thick mucus also blocks the ducts of the pancreas, preventing enzymes from reaching the intestines to digest food. Therefore, persons with CF must consume a large number of artificial enzymes (on average 20 pills a day) with every meal and snack, to help them absorb adequate nutrition from their food. They must also follow a demanding daily routine of physical therapy to keep the lungs free of congestion and infection.

How is it manifested?

  • difficulty breathing
  • constant cough which expels thick mucus
  • excessive appetite, with weight loss
  • bowel disturbances
  • skin which tastes salty
  • repeated or prolonged bouts of pneumonia
  • failure to thrive

Who is affected?

It is estimated that 1 in every 3,600 children born in Canada has Cystic Fibrosis. CF is a genetic disease that occurs when a child inherits an abnormal gene from each parent. When both parents are carriers, there is a 25 percent chance that their child will be born with Cystic Fibrosis. There is also a 50 percent chance that the child will be a carrier and a 25 percent chance that the child will neither be a carrier nor have cystic fibrosis.

How is it diagnosed or detected?

If a physician suspects CF, he will probably suggest a “sweat test”. This simple and painless test measures the amount of salt in the sweat. A high salt level, along with other symptoms, points to the presence of Cystic Fibrosis.

Increasingly, genetic tests are being used in the diagnosis of the disease. Genetic tests are also used to diagnose CF prenatally.

Approximately 60% of patients are diagnosed in the first year of life, and 90% by 10 years of age.

Cri du Chat Syndrome

Fact Sheet

What is Cri du Chat Syndrome?

Cri du Chat Syndrome arises from the absence of a particular portion of Chromosome 5. The absence of genetic material is called a deletion. Children born with this deletion have a characteristic mewing cry that is thought to be caused by abnormal development of the larynx (the organ containing the vocal chords). For this reason, the disorder is called Cri du Chat (or Cat’s Cry) Syndrome. In reference to the deletion and the area where it occurs, the disorder is also called 5p- (5 p minus) Syndrome. Children with this syndrome have physical abnormalities, language and motor skill difficulties, and varying degrees of intellectual disabilities. Cri du Chat Syndrome is a very rare disorder.

How is it manifested?

  • high-pitched cry (identified as a cat-like cry)
  • low birth weight
  • poor muscle tone (hypotonia)
  • microcephaly (small head size)
  • micrognathis (small jaw)
  • hypertelorism (wide spaced eyes)
  • round face
  • epicanthal folds (small skin folds on the inner corners of the eyes)
  • low set ears
  • feeding difficulties
  • delay in walking
  • hyperactivity
  • scoliosis
  • language difficulties
  • intellectual disabilities
  • organ defects

Who is affected?

The estimated prevalence is about 1 in 20, 000-50,000 newborns. Most cases of Cri du Chat Syndrome are not inherited. The deletion mostly occurs at random during the formation of reproductive cells (eggs or sperm) or in early fetal development. However, about 10 per cent of people affected inherit a chromosome abnormality/rearrangement called a balanced translocation from an unaffected parent. Balanced translocations usually do not cause any health problems. When a child inherits the unbalanced translocation, however, there is a possibility of a chromosal rearrangement with extra or missing genetic material. Individuals with Cri du Chat Syndrome are missing genetic material from the short arm of Chromosome 5.

How is it diagnosed or detected?

During infancy, a diagnosis of Cri du Chat Syndrome is strongly suspected if the characteristic cat-like cry is heard. If a child has this unusual cry, or other features seen in Cri du Chat Syndrome, chromosome testing should be performed. Chromosome analysis provides a definitive diagnosis of Cri du Chat Syndrome and can be performed from a blood test. Chromosome analysis, also called “karyotyping,” involves staining the chromosomes and examining them under a microscope. In some cases the deletion of material from Chromosome 5 can be easily seen. In other cases, further testing must be performed. Fluorescence In-Situ Hybridization (FISH) is a special technique that detects very small deletions. The majority of the deletions that cause Cri du Chat Syndrome can be identified using the FISH technique.
