Abstract: | Summary Two brothers with duplication of the distal segment of 22q inherited from a t(6;22)(q27;13) translocation carrier mother presented with intraurine growth retardation, congenital hydrocephalus, cleft palate, genital hypoplasia with cryptorchidism and hypospadias, and similar facial features including mongoloid position of eyeaxes, hypertelorism, small nose with prominent bridge, prominent upper lip, and small mandible. In addition the second sib revealed renal hypoplasia, arrhinencephaly and pentalogy of Fallot. The patients died at ages eight days and one day, respectively. The two brothers appear to be the first instances of familial trisomy 22q13qter. |
