Oral clefts (cleft lip and palate)
Causes Grouped by strength of evidence
Good Evidence | Limited Evidence |
Notes
Parental pesticide exposure in the home and occupationally in agricultural workers has been associated with oral clefts. Environmental exposure to alcohol, tobacco smoke or dioxins may interfere with gene expression (TGFA and TGFB3) required for palate and lip formation. Trihalomethanes, including chloroform, are found in drinking water as by-products of disinfection (usually by chlorine). Carbon tetrachloride and trichloroethylene as drinking water contaminants.
