Abstract
We have evaluated four individuals from two unrelated families with a similar multiple congenital anomalies/mental retardation (MCA/MR) syndrome due to partial duplication of chromosome 1q and possible deletion 18p. In both families the mothers and several relatives were carriers of the balanced translocation rep t(1;18) (q42;p11). The features which the four have in common are relative macrocephaly, prominent forehead, micrognathia, and highly arched palate; three of the four individuals have short stature, scoliosis, kyphosis, hirsutism, camptodactyly, sacral dimple, repaired inguinal hernias, and eye abnormalities. Reproductive histories of five balanced translocation carriers in these families indicate that they have a high risk of spontaneous abortions and infants with multiple malformations.Keywords
