This finding is similar to the findings of 2 previous articles where they reported no significant association of this polymorphism with AA in the Iranian and Jordanian populations.[17,20] However, Seleit et al reported that there was a significant association with AA in the Egyptian population.[28] A positive association was observed by Tojo et al between the number of interferon-producing cells (IL17) and the severity and progression of alopecia.[32] However, our findings showed that there was no significant association found between IL17A gene and the development of AA. Here, IL17A is linked to alopecia.
