In the meta-analysis for endometriosis, rs12700667 on chromosome 7 remained the sentinel SNP after imputation, but imputed SNPs at the 5′ end of WNT4 had stronger signals than the best signal from the GWAS (rs7521902) located 20 kb upstream of the WNT4 (Nyholt et al., 2012; Albertsen et al., 2013). This evidence concerns the gene WNT4 and endometriosis.
