Detailed explanation-1: -Cri-du-chat syndrome is caused by a deletion of the end of the short (p) arm of chromosome 5. This chromosomal change is written as 5p-.

Detailed explanation-2: -Cri du chat syndrome is a chromosomal disorder caused by a partial deletion (monosomy) of a varying length of the short arm (p) of chromosome 5. Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual.

Detailed explanation-3: -Cri du chat syndrome is rare. It is caused by a missing piece of chromosome 5. Most cases are believed to occur during the development of the egg or sperm. A small number of cases occur when a parent passes a different, rearranged form of the chromosome to their child.

Detailed explanation-4: -Cri du chat syndrome-also known as 5p-syndrome and cat cry syndrome-is a rare genetic condition that is caused by the deletion (a missing piece) of genetic material on the small arm (the p arm) of chromosome 5. The cause of this rare chromosomal deletion is unknown.
