Furthermore, we investigated the genome-wide significant lead variants in the FinnGen cohort (release 9) and found that the lead variants on chromosome 12 (TBX3) and chromosome X (FRDM7/RAP2C) were also associated with endometriosis, and the loci on chromosomes 6 (PHACTR2), 10 (ZEB1) and X (FRDM7/RAP2C) were associated with uterine fibroids (Table 1 and Supplementary Fig. 2b). Here, TBX3 is linked to endometriosis.
