title: A recent aetiological study on facial clefting in Hungary.
abstract: A case-control epidemiological and family study was organized of 2024 index patients born between 1970 and 1976 affected by isolated cleft lip +/- cleft palate, isolated posterior cleft palate and multiple congenital abnormalities including facial clefting and of their matched control cases. The specific rate of affected parents and sibs was 2.4% and 4.2% in the isolated cleft lip +/- cleft palate sample, while 2.2% and 3.2% in the isolated posterior cleft palate group. The proportion of polygenic liability was about 77 +/- 8% in isolated cleft lip +/- cleft palate cases. Among teratogens, the triggering impact of certain anticonvulsants was confirmed.
