Cri-du-Chat syndrome is the result of a monosomy (2n=45,5-) or segmental aneuploid deletion of a portion of the short arm (2n=46,5p-) of Chromosome 5.
Symptoms include a characteristic high-pitched cry ("cat cry"), low
birth weight, poor muscle tone, microcephaly, and mental retardation.
Children respond well to the home environment, and institutionalization
is now less common.
