B group short-arm deletion syndrome

Abstract

Three cases of the cat-cry syndrome are reported and the literature on Bp- syndromes is reviewed. Although the 4p- and 5p- syndromes have many overlapping features, the cleft lip-palate, seizures, iris coloboma, and other features of the 4p- syndrome, as well as absent cat-cry, are frequently sufficient to distinguish between the 4p- and 5p- syndromes.
