The G syndrome--additional observations.

We are reporting the second lethal case of G syndrome occurring in a female. The developmental defects in this patient included posteriorly angulated auricles, bifid tip of tongue with a long frenulum, hypoplasia of the epiglottis and larynx, rocker bottom feet, and hypertrophied labia majora and clitoris. Additional anomalies not previously reported in the G syndrome were circumvallate placenta, and incompletely perforated hymen.
