STAT4

A gene on chromosome 17q21.31 that encodes a member of the STAT family of transcription factors, which are phosphorylated by receptor-associated kinases in response to cytokines and growth factors, including IFNs, EGF, IL5, IL6, HGF, LIF and BMP2. The STAT4 protein product mediates responses to IL12 in lymphocytes, and regulates the differentiation of T helper cells.

The rs7574865 and rs10181656 SNPs in the third intron of the STAT4 gene were amplified by polymerase chain reaction (PCR), and the 5'-TTATGGAAAATTACATGAGTGTG-3' and 5'-GCAAATCTTTGTAAAAAGTCAA-3' primers were used to generate a region of 156 bp in the STAT4 gene that could be used in the subsequent genotyping reactions of the rs7574865 polymorphism.

The genotyping of the STAT4 rs7574865 and rs10181656 SNPs was performed using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis.
