Malpuech syndrome: three patients and a review.

We describe three patients with Malpuech syndrome from two families. Previously, 10 patients from 6 families have been reported. Consanguinity in two families suggests autosomal recessive inheritance. Growth retardation, mental retardation, cleft lip, and/or palate, hypertelorism, urogenital abnormalities, and caudal appendage are the key features. Although the spectrum of the features in the reported patients is variable, we do think this syndrome represents a distinct entity. Chromosomal anomalies should be carefully searched for. We discuss differential diagnosis and possible candidate genes and propose diagnostic criteria for Malpuech syndrome.
