Two RFLPs at the TGFA locus were studied in 39 unrelated Chilean (Caucasoid-Mongoloid) patients with non-syndromic cleft lip/palate [CL(P)] and 51 control individuals. A highly significant association between BamHI A2 allele and CL(P) was detected ({chi}{sub 2} = 6.00; P = 0.014), while no association was found between TaqI RFLPs and clefting. No significant differences were found when comparing genotypes by type of cleft and a positive or negative family history of clefting. Our results seem to support rather definitively the association between TGFA and clefting but not support the hypothesis that TGFA is a major causal gene of CL(P). 29 refs., 5 tabs.
