Results from genome-wide association studies (GWAS) and transcriptome sequencing have demonstrated that genes located in the 1p36 region are important in both endometriosis and endometriosis-associated cancer development. Therefore, we tested the hypothesis that SNPs in two tumor-suppressor genes (CHD5 and ARID1A) in the 1p36 region are associated with endometriosis. METHODS: Allele frequencies of SNPs were investigated in 1685 Caucasian women consisting of 947 women with endometriosis and 738 controls. Peripheral blood samples were retrieved, DNA extracted and allelic frequencies of SNPs in two tumor-suppressor genes (CHD5 and ARID1A) were analyzed using TaqMan Open Array technique. RESULTS: Associations were observed for 3 SNPs in the CHD5 gene: rs1883603 (OR 1.31, 95% CI 1.00-1.71), rs9434741 (OR 1.41, 95% CI 1.16-1.71) and rs17436816 (OR 1.24, 95% CI 1.02-1.50). After correction for multiple comparisons, rs9434741 (CHD5) remained significantly associated with endometriosis (p<0.01). No associations were detected for ARID1A. CONCLUSIONS: In this Caucasian population, endometriosis seems to be associated with the tumor-suppressor gene CHD5. Our findings support recent data, suggesting that the 1p36 region plays an important role in endometrios. To validate these data, replication in an independent population is warranted.
