Rs4796793

rs4796793, a SNP in the 5' region of the signal transducer and activator 3 STAT3 gene, has been linked in a study of 75 Japanese patients to (successful) response to interferon-alpha immunotherapy for metastatic kidney cancer.

From this paper :

"... rs4796793 was the most significant predictor of IFN-alpha response (odds ratio [OR] = 2.73; 95% CI, 1.38 to 5.78). The highest OR was shown in the (C;C) genotype ... compared to the (G;G) + (G;C) genotypes (OR = 8.38, 95% CI, 1.63 to 42.96)."
