Liveborn trisomy 22: report of one case.

A case of trisomy 22 liveborn female baby with multiple congenital anomalies is described. Physical manifestations included failure to thrive, hypotonia, pre-auricular sinus, low set ears, hypertelorism, posterior low hair line, micrognathia, cleft palate, congenital heart disease, imperforated anus with anovulvar fistula, contracted pelvis and bilateral rocker-bottom feet. The infant died at two months of age. Cases of trisomy 22 usually present with many severe malformations, and they rarely survive to term. A review of the literature is presented to delineate this chromosome disorder.
