The Cri-du-chat Syndrome (CdCs) is a rare genetic syndrome first described by Jerome Lejeune in 1963, characterized mainly by the high pitched cat like cry. The prevalence of CdCs was varied in between 1:15,000 to 1:50,000 in live birth and more common in female gender with a ratio of 4:3 [1, 2] .The condition may be accompanied by developmental and cognitive delays, poor spatial awareness, impaired ambulation, and poor sensori-motor skills. Other associated problems described include cardiovascular, renal, gastrointestinal, neurological abnormalities, preauricular tags, syndactyly, hypospadias, and cryptorchidism.1 Recent literatures show that autistic behaviours are common in various genetic disorders [3].Fatigue level of children with cri du chat syndrome was associated with the expression of autistic features [4].
