Variable expression in Pfeiffer syndrome.
Abstract
A female infant with Pfeiffer syndrome (acrocephalosyndactyly V) is presented. Her mother has no limb malformations, but has craniofacial features with strongly suggest that she is also affected, although more mildly. This family indicates that wide intrafamilial variation of Pfeiffer syndrome is possible and suggests that without detailed investigation mildly affected subjects can remain undiagnosed, which may lead to erroneous genetic counselling.
