Incidence of cleft lips, palates rising.
About 1:700 live human births are affected by cleft lip and palate. Socio-economic factors--teenage pregnancies, pregnancies in women older than 35, increased consumption of teratogens during early months of pregnancy--have resulted in increased numbers of congenital malformations in the United States.
