Meta-analysis of the 1184 HNF1B region SNPs genotyped or imputed in the four Caucasian datasets [iCOGS fine-mapping, Australian National Endometrial Cancer Study (ANECS), Studies of Epidemiology and Risk factors in Cancer Heredity (SEARCH) and National Study of the Genetics of Endometrial Cancer (NSECG GWASs)] and passing our quality control measures identified 18 SNPs that reached genome-wide significance (P < 5.0 × 10−8) (Table 2; results for individual sample sets provided in Supplementary Material, Table S2). The gene discussed is HNF1B; the disease is endometrial cancer.
