Pseudotrisomy 13 syndrome : A case report.

We report on a male baby with microcephaly, holoprosencephaly of alobar type with sigle ventricle, cyclopia, proboscis, poorly developed testes, and clenched hands without polydactyly, suggestive of trisomy 13 syndrome. However, the cytogenetic study disclosed 46,XY. The case presented here very well represents pseudotrisomy 13 syndrome and signifies the value of cytogenetic study and genetic counseling.
