In 1964, Bowen et al1 described two siblings with congenital abnormalities including (1) marked hypotonia, (2) multiple renal cortical cysts, (3) glaucoma, (4) hepatomegaly, (5) hypoprothrombinemia, (6) developmental abnormalities of the brain, (7) congenital stippled epiphyses, and (8) a clinical appearance suggestive of Down's syndrome. Since the sibs in this family were Zellweger's patients, his name is now used for the designation of this syndrome.
In the present paper two siblings are recorded who display similar clinical features. The purpose of this article is to show some other unusual features of this syndrome and to point out close similarities as well as differences between this condition and chondrodystrophia calcificans congenita (Conradi's disease).
