An additional mechanism with potential impact on the declined expression of the TGFBR3 gene involves three intronic SNPs, i.e., rs12566180 (c.-114 + 2392C > T) and rs2296621 (c.2285 − 99G > T), which correlate with TGFBR3 transcript loss in endometrial cancer. Here, TGFBR3 is linked to endometrial cancer.
