Title: In a Vietnamese population, MSX1 variants contribute to cleft lip and palate. Author: Suzuki Y, Jezewski PA, Machida J, Watanabe Y, Shi M, Cooper ME, Viet le T, Nguyen TD, Hai H, Natsume N, Shimozato K, Marazita ML, Murray JC. Journal: Genet Med; 2004; 6(3):117-25. PubMed ID: 15354328. Abstract: PURPOSE: To identify causes of nonsyndromic cleft lip and palate in a Vietnamese population. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.[Abstract] [Full Text] [Related] [New Search]
