New mental retardation syndrome with hearing impairment,distinct facial appearance,and skeletal anomalies

We present 2 unrelated children with a distinct pattern of anomalies, including mental retardation, hearing impairment, unusual facial appearance, and skeletal defects. Both children have severe behavior disturbance and hyperactivity. The characteristic facial findings include a broad mouth, broad nasal bridge, mildly anteverted nares with a fleshy nasal tip, and deep nasolabial folds. Skeletal findings include mild to moderate short stature, dysharmonic maturation of epiphyseal ossification centers in the hands, and mild scoliosis. © 1992 Wiley-Liss, Inc.
