Growth deficiency, facial anomalies, and brachydactyly (Frías syndrome): a second family.

A second family with the condition first described by Frías et al. in 1975 is presented. Those authors examined a mother and her son affected with short stature, facial anomalies (epicanthic folds, downward palpebral fissures, hyperthelorism, and eyelid ptosis), cup-shaped and posteriorly rotated ears, hand and foot defects, and delayed bone age. In the family we are presenting here, a girl, her mother, the mother's brother, and the propositus' maternal grandmother, were affected. This supports autosomal dominant inheritance, as proposed by (Frías et al. [1975] BDOAS 11:30-33), although with variable expressivity.
