Furthermore, the CC genotype at rs1546124 was associated with increased risk for cleft lip with or without cleft palate (CL/P; OR, 2.11; 95% CI, 1.41-3.15; p(correct) = 1.5 × 10(-4) ) and for cleft palate only (CPO; OR, 2.93; 95% CI, 1.69-5.07; p(correct) = 5.4 × 10(-4) ), whereas the T allele of rs4783099 was associated with decreased risk for CPO.
We also found association of SNP rs1546124 with cleft palate alone (CP) in South Americans (Guatemala and ECLAMC) and combined Hispanics (Guatemala, ECLAMC, and Texas Hispanics; p = .03 for both comparisons) and with both cleft lip with cleft palate (CLP; p = .04) and CL(P) (p = .02) in North Americans.
