Title: A new syndrome of dwarfism, brachydactyly, nail dysplasia, and mental retardation in sibs. Author: Tonoki H, Kishino T, Niikawa N. Journal: Am J Med Genet; 1990 May; 36(1):89-93. PubMed ID: 2333912. Abstract: We describe a new multiple congenital anomaly/mental retardation (MCA/MR) syndrome in chromosomally normal sibs. Both had microcephaly, a "coarse" face with synophrys, ear anomalies, type B brachydactyly, nail dysplasia, skeletal anomalies, dwarfism, and mental retardation. Their mother had nail dysplasia, mild mental retardation, and short stature. An uncle, a younger brother of the mother, died at 17 years of age and also had a "coarse" face, digital anomalies, dwarfism, and severe mental retardation. The malformation complex in this family apparently has not been described previously, and the manifestations of the patients do not correspond to those of any known malformation syndrome. The disorder may be attributable to the pleiotropic effect of an autosomal dominant or an X-linked semidominant gene.[Abstract] [Full Text] [Related] [New Search]
