“…The SNPs on the promoter of a gene may alter the gene expression however the SNPs in the intron regions could alter the production of mature mRNA by interfering with the splicing process (Mobasseri et al, 2019;Zamani-Badi et al, 2019). But, the missense mutations could alter the structure and function of proteins (Noureddini et al, 2018;Bafrani et al, 2019) what may be true for GSTP1-Ile105Val genetic variation. Evaluation of the impacts of genetic variations by biological experiments is a very difficult process and evaluation of these impacts could be much easier with the in silico tools (Tameh et al, 2018;Zamani-Badi et al, 2018).…”
