Autosomal recessive cerebellar hypoplasia and endosteal sclerosis: a newly recognized syndrome.

We describe a brother and sister and an unrelated boy with congenital cerebellar hypoplasia and endosteal sclerosis. All 3 children presented with ataxia and developmental delay, and were found to have microcephaly, short stature, oligodontia, strabismus, nystagmus, and congenital hip dislocation. A previously published case is reviewed. The disorder appears to represent a newly recognized autosomal recessive syndrome.
