This study provides clinical and molecular characterization for 12 prenatal case of Cri‐du‐chat syndrome (CdCS) and genotyping‐phenotyping analysis for these cases.

Sayangnya, ini termasuk kondisi cacat lahir pada bayi yang disebut dengan sindrom cri du chat. Kondisi ini disebabkan karena adanya kelainan pada gen, tetapi bukan termasuk kondisi keturunan. Cri-du-chat is a rare genetic disorder discovered by Jerome Lejeune in 1963. It is caused by the deletion of genetic material on chromosome five, an autosomal chromosome. The deletion occur on the "p" arm of the chromosome. Scientists do not know the reason why this chromosome deletion occurs.

This suggests that Cri du chat symptoms may be driven by epigenetic mis-regulation during development. Results. DNA methylation was measured at 850,000 CpG sites from blood samples of eight Cri du chat patients and matched controls by microarray. Introduction. Cri du chat syndrome (CdCS), also known as 5p minus syndrome or cat cry syndrome, is a chromosomal disorder that was first described by Lejeune et al in 1963 [].A total or partial deletion of the short arm of chromosome 5 (5p-) results in an anatomically abnormal larynx causing the distinctive high-pitched, cat-like cry for which the disorder is named []. .
