• Three brothers had a syndrome of hypospadias and mental retardation in association with microcephaly, craniofacial dysmorphism, joint laxity, and beaked nails. No other family members were affected, and this previously undelineated condition appears to be inherited in either an autosomal recessive or X-linked recessive mode.
