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 cry. The disorder is characterized by intellectual disability and delayed development, low birth weight, and failure to thrive. Cri-du-chat syndrome is a chromosomal disorder caused by a deletion of the short arm of chromosome 5. The disease severity, levels of intellectual and developmental delay, and patient prognosis have been related to the size and position of the deletion. Concerned fans believe Chrisean Rock and Blueface's child is suffering from Cri Du Chat Syndrome. According to searches, Cri Du Chat Syndrome is a rare genetic disorder that happens due to a partial chromosome deletion on chromosome 5. Its name is a French term referring to the characteristic cat-like cry of affected children. Introduction. Le syndrome du Cri du Chat (Cri du Chat syndrome, CdCS) est une anomalie chromosomique résultant d ' une délétion de taille variable de l'extrémité du bras court du chromosome 5 (5p), incluant une région critique située en p15.2 [].Il représente une des délétions chromosomiques les plus fréquentes, son incidence dans la population générale est de 1/20 000 à 1/50 Cri du chat syndrome is present from birth and affects growth and development. Infants with this condition often have a high-pitched cat-like cry, small head size, and a characteristic facial appearance. symptoms and confirmed by the results of genetic testing. Treatment is focused on managing the symptoms.[15498][15500][15501] Synonyms The first research studies with people with Cri du Chat syndrome suggested that almost all individuals had a profound degree of intellectual disability. A profound degree of disability means a person may need significant support with day to day living tasks such feeding, washing and dressing. These early studies may have been misleading. Cri du Chat Syndrome (CdCS) was first described c by J. Lejeune et al., in 1963 as a genetic, chromosomal disease that resulted from the deletion of variable sizes in the short arm of chromosome 5 (Orphanet). Behavioral Symptoms also develop into the phenotype of Cri du Chat-diseased children. These children often have hyperactivity Cri du Chat Syndrome Description: Cri du Chat syndrome results from missing a piece of chromosome 5. Symptoms include a high-pitched cry that sounds like a cat, downward slant of the eyes, partial webbing or fusing of fingers or toes, and slow or incomplete development of motor skills. Cri-du-chat syndrome was first described by Lejeune et al. (1963) as a hereditary congenital syndrome associated with deletion of part of the short arm of chromosome 5. The deletions can vary in size from extremely small and involving only band 5p15.2 to the entire short arm. Although the majority of deletions arise as new mutations, approximately 12% result from unbalanced segregation of The symptoms of cri du chat syndrome vary among individuals. The variability of the clinical symptoms and developmental delays may be related to the size of the deletion of the 5p arm. The clinical symptoms of cri du chat syndrome usually include a high-pitched cat-like cry, mental retardation, delayed development, distinctive facial features dsMTs4S.
