On the other hand, we found significant associations with genotyped SNPs in the 6p12.2 region in chromosome 6: rs3748067>C inIL17A and rs763780>C in IL17F. While few studies have explored the association of rs3748067 in IL17A with the cancer risk but not with AIDs [31, 32], rs763780 in IL17F was associated with many AIDs such rheumatoid arthritis in Tunisian population [33]. This evidence concerns the gene IL17A and AIDS.
