A case of cri-du-chat associated with cataracts and transmitted from a mother with a 4-5 translocation.

The cat cry syndrome (cri-du-chat) was first described by Lejeune et al (1963) in a group of patients with mew-like cry and other congenital anomalies who had a partial deletion of the short arm of a B group chromosome. This partially deleted B group chromosome was subsequently found to be No. 5 by autoradiographic studies performed by German et al (1964).
