Familial syndrome resembling Aarskog syndrome.

Aarskog(-Scott) syndrome (AAS) is characterized by short stature, and facial, limb, and genital anomalies. AAS can be an X-linked condition caused by mutations in the FGDI gene, but there is evidence that an autosomal dominant or recessive form also exists. We report on a Chinese family in whom several members have manifestations of AAS, but differ in limb anomalies and show additional characteristics. FGD1 sequencing and linkage analysis excluded FGD1 as the cause in this family. A common known submicroscopic chromosome imbalance is less likely. Both autosomal dominant and recessive patterns of inheritance remain possible. (C) 2010 Wiley-Liss, Inc.
