We report two siblings with congenital generalized hypertrichosis and 
distinctive facial appearance consistent with the dysmorphic facial features 
described in Ambras syndrome. The patients were born to non-consanguineous, 
phenotypically normal parents. This is the first report of affected siblings and 
could be explained by either autosomal recessive inheritance or by germline 
mosaicism for an autosomal dominant gene. We compared the phenotype of our 
patients to descriptions of reported cases and discuss phenotypic variability.
