Abstract

BACKGROUND: Mutations of the MSX1 gene may contribute to non-syndromic forms of cleft lip and/or cleft palate. AIM: To search for mutations of MSX1 coding regions, including one highly conserved non-coding region in the single intron, among Chilean patients with cleft lip/palate. PATIENTS AND METHODS: We studied 45 patients with cleft lip/palate and their parents. Oral mucosa samples were obtained with a swab. DNA was extracted and amplified by PCR. RESULTS: Two missense mutations (G16D and G34A) were identified in this study that may be useful for future admixture studies. The G16D mutation appears to disrupt a possible splicing site and may contribute to clefting in this population. CONCLUSIONS: Rare MSX1 mutations are found in some cases of cleft lip and/or cleft palate but others remain to be found most likely in other regulatory regions of the gene.
