CRI DU CHAT SYNDROME | ||
ALTERNATE NAMES |
5p-Syndrome; Cat's Cry Syndrome; Le Jeune Syndrome; Chromosome 5p-Syndrome; 5p deletion syndrome |
|
DESCRIPTION |
Cri-du-Chat syndrome is a hereditary chromosomal condition that results when a piece of chromosome 5 is missing. Infants with this condition often have a high-pitched cry that sounds like that of a kitten or cat. The disorder is characterized by intellectual disability and delayed development, low birth weight and failure to thrive. There are several distinctive physical features present such as: small head, low-set ears, wide-set eyes, small jaw and partial webbing or fusing of fingers and toes, weak motor skills and muscle tone. Some children with cri-du-chat syndrome are also born with cardiac defects, scoliosis and cleft palates. Destructive behavior, self-mutilation and aggression are common. |
|
DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM CODING |
Genetic tests can show a partial deletion of chromosome 5. Skull x-ray may reveal an abnormal angle to the base of the skull. ICD-9: 758.31 Cri-du-chat syndrome |
|
ONSET AND PROGRESSION |
The outcome varies, but intellectual disability is usual. Half of those children affected learn sufficient verbal skills to communicate. The cat-like cry becomes less apparent over time. |
|
TREATMENT |
No specific treatment is available for this condition. The intellectual disability must be addressed, and counseling is recommended for the parents/caregivers. |
