In another investigation, a partial loss of BAF250a (ARID1A) expression was exhibited in 36% of the cases of rectovaginal deep infiltrating endometriosis (DIE), 40% of endometriosis lesions in pelvic sentinel lymph nodes (PSLNs), 30% of ovarian endometriomas, and 25% of control endometrium samples. Here, ARID1A is linked to endometriosis.
