To identify causes of nonsyndromic cleft lip and palate in a Vietnamese population.


In this study, 175 families with at least one case of cleft lip and/or palate were studied using the candidate genes TGFA, MSX1, and TGFB3.


Transmission distortion for alleles of MSX1 were demonstrated for the whole population and two missense mutations were identified, including one (P147Q) that is found in approximately 2% of the population. The P147Q appears to arise from a founder individual based on shared haplotypes in unrelated families.


MSX1 contributes to nonsyndromic clefting in a Vietnamese population, and consistent with other studies, identifiable mutations in this gene cause about 2% of cases of nonsyndromic clefting.
