Abstract

Abstract : Three RFLPs at the TGFA locus were studied in 60 unrelated British Caucasian subjects with non-syndromic cleft lip/palate and 60 controls. A highly significant association between the TaqI RFLP and the occurrence of clefting was found (chi 2 = 15.04, p = less than 0.001). No significant association was found with the two other RFLPs studied (BamHI and RsaI). Haplotypes derived from the three RFLPs at the TGFA locus also showed an over-representation of the C2A2B2 haplotype in cases compared to controls. Analyses of genotypes according to type of cleft and the presence or absence of a family history of clefting were also carried out. These results provide further support for the role of TGFA as a gene of major effect in the development of orofacial clefts in humans.
