KIFAP3 and endometriosis: Importantly, on the one hand, BMI has inverse correlations with endometriosis (low BMI is a risk factor for the disease [65,66,67,68]), and there are works in the literature that show the association of BMI-related polymorphisms/genes (GHRH, GRB14, LHCGR, KIFAP3, WNT4, CAB39L, etc.)with endometriosis [69]; on the other hand, BMI also has inverse correlations with the SHBG level in the organism [70,71,72].
