title: [The FG syndrome (McK 30545). Description of 2 cases with subaortic stenosis].
abstract: This paper reports on two brothers affected by FG syndrome (a rare X-linked syndrome with multiple congenital anomalies and mental retardation) and subvalvular aortic stenosis of the discrete type. This is a previously unrecognized association. The FG syndrome was firstly described by Opitz and Kaveggia in 1974. Nearly 20 cases have been reported: congenital heart diseases previously reported are atrial septal defect, ventricular septal defect and hypoplastic left heart. The clinical appearance of the two cases we have observed was that of mental retardation and typical features including abnormal facies (dolicocephaly, frontal prominence, poorly modeled auricles, micrognathia, prominent lower lip and lack of expression), anteriorly displaced anal opening, clinodactyly, great broad toes. A chromosome study showed a normal 46 XY constitution. Discrete subvalvular aortic stenosis was diagnosed by typical physical and echocardiographic findings.
