Jerome Lejeune discovered the disorder in 1963

Meiosis results in the formation of four genetically different haploid cells. An error occurs during the process of meiosis with the 5th chromosome to cause Cri-du-chat syndrome. Fertilization is the union of haploid gametes to produce a diploid zygote. The deletion of the 5th chromosome occurs in the production of sex cells and therefore will transfer the syndrome to the zygote it creates.
