This is the second reported case of a child with holoprosencephaly and trisomy 21. The first case was born to a diabetic woman; in our case, there was no evidence of diabetes in the mother. Most of the distinctive facial features of Down syndrome were obscured by the presence of cyclopia and a supraorbital proboscis in this infant. The relevance of chromosome analysis in cases with holoprosencephaly is discussed.
