Cri du Chat condition only affects about 1 in 45,000 new infants and generally occurs more in females than males, and strikes regardless of ethnicity.
One condition caused by chromosomal deletion is Cri-du-chat syndrome, which results from a deletion on the short arm of chromosome 5. This syndrome is characterized by intellectual disability, distinctive facial features, and a cat-like cry in infants.
Cri-du-chat syndrome is a genetic disorder caused by a deletion in chromosome 5. It is not typically inherited in a Mendelian pattern but rather occurs sporadically. However, if a parent carries a balanced translocation involving chromosome 5, there may be a risk of passing the deletion on to offspring.
Most cases of cri-du-chat syndrome are not inherited. The deletion of part of a chromosome occurs most often as a random event during the formation of reproductive cells (eggs or sperm) or in early fetal development. Affected people typically have no history of the disorder in their family.About 10 percent of people with cri-du-chat syndrome inherit the chromosome abnormalityfrom an unaffected parent. In these cases, the parent carries a chromosomal rearrangementcalled a balanced translocation, in which no genetic material is gained or lost. They however show no signs of the disorder.Balanced translocations usually do not cause any health problems; but they can become unbalanced as they are passed to the next generation.
Cat cry syndrome, also known as Cri du chat syndrome, is caused by a deletion on the short arm of chromosome 5. This genetic abnormality is considered sporadic and not linked to the X or Y chromosome.

Cri du Chat Syndrome or Chromosome 5p- is a chromosomal condition that results in brain abnormalities.
Some organizations that support individuals with Cri-du-Chat syndrome include the National Organization for Rare Disorders (NORD), the Cri du Chat Syndrome Support Group, and Unique (Rare Chromosome Disorder Support Group). These organizations provide information, resources, and support for individuals with Cri-du-Chat syndrome and their families.
Cri Du Chat syndrome was first discovered by a Frenchman, a geneticist named Jerome Lejeune in the year 1963. He was also a pro-life pediatrician who helpe in the discovery of the connection between chromosome abnormalities and diseases. He devoted a major part of his career treating children affected by Down's syndrome.
