The clinical findings are described in three siblings with a syndrome of microcephaly and multiple congenital abnormalities. All three infants had congenital anomalies of the limbs, described as flexion deformities. Infant 2 showed atrophic gyri and absence of the corpus callosum, with atrophy of cerebrum, cerebellum, and pons. Infant 2 exhibited unusual canine facies. Chromosomal studies were normal on infant 3 (leucocyte and skin cultures). Leucocyte cultures from the mother and father revealed no cytogenetic abnormality.
