Replication of 13q31.1 association in nonsyndromic cleft lip with cleft palate in Europeans.

ABSTRACT: Genome wide association (GWA) studies have successfully identified at least a dozen loci associated with orofacial clefts. However, these signals may be unique to specific populations and require replication to validate and extend findings as a prelude to etiologic SNP discovery. We attempted to replicate the findings of a recent meta-analysis of orofacial cleft GWA studies using four different ancestral populations. We studied 946 pedigrees (3,436 persons) of European (US white and Danish) and Asian (Japanese and Mongolian) origin. We genotyped six SNPs that represented the most significant P-value associations identified in published studies: rs742071 (1p36), rs7590268 (2p21), rs7632427 (3p11.1), rs12543318 (8q21.3), rs8001641 (13q31.1), and rs7179658 (15q22.2). We directly sequenced thr
