IL17A and breast cancer: In addition, previous studies with rs3748067 variant in the IL-17A gene described its notable association with a variety of cancers in multiple ethnicities, such as breast cancer [20], cervical cancer [21–26], colorectal cancer [27, 28, 41], gastric cancer [29, 30], and others. Based on the previous research, we performed this case-control study that reported the correlation of IL-17A rs3748067 polymorphism with the risk of cervical malignancy.
