Cataract, hypertrichosis, and mental retardation (CAHMR): a new autosomal recessive syndrome.

We have studied 2 Egyptian sibs (the offspring of normal first cousins) with congenital cataract, hypertrichosis, mental retardation, and normal chromosomes. Review showed that the condition of our patients was not similar to any previously reported entity. POSSUM lists 84 syndromes with any of the above 3 main traits. Two disorders with cataract and mental retardation, Martsolf syndrome and Mollica-Pavone-Anterer syndrome, have overlapping manifestations and therefore are particularly differentiated from our cases. We suggest that the association of congenital cataract, hypertrichosis, and mental retardation observed in this report represents a new autosomal recessive syndrome.
