Popliteal Pterygium Syndrome

Reference work entry

In 1968, Gorlin et al. described an autosomal dominant form of popliteal pterygium syndrome (PPS), a syndrome comprising cleft lip and palate, popliteal and intercrural pterygia, and digital and genital anomalies. Van der Woude syndrome (VWS) is one of the most common oral cleft syndromes. It accounts for about 2% of all cleft lip and palate cases. Both syndromes are caused by IRF6 mutations.

In 1972, Bartsocas and Papas reported on four sibs of third-cousin parents with a severe, presumably autosomal recessive form of popliteal pterygium syndrome.
