• An infant previously reported to have psychomotor retardation and multiple congenital anomalies including hypotonia, failure to thrive, peculiar facies, low-set ears, micrognathia, and cryptorchidism in association with monosomy due to a D/E (13-15/17-18) translocation has been reexamined. Further cytogenetic studies, using fluorescent techniques, indicate the translocation involves chromosomes 15 and 17.
Only two other patients with partial monosomy due to grossly similar D/E translocations have been reported. On reexamination, the translocation in one has recently been found to involve chromosomes 15 and 18 and that in the other has not been further defined.
