WNT4 and endometriosis: Considering loci with genome-wide significance for each trait, two endometriosis loci have lower P values than expected by chance in the WHRadjBMI GWAS: intergenic 7p15.2 and WNT4, and two of the 16 WHRadjBMI loci had P < 0.01 in the endometriosis GWAS: intergenic 7p15.2 and GRB14 (Rahmioglu et al., 2015).
