This study aimed to investigate the impact of functional SNPs (fSNPs) in GSTP1 on the risk of CRC, as well as their structural and functional consequences. We analyzed a total of 126 selected GSTP1 SNPs, including fSNPs <em>rs1695 A > G</em> (I105V) and <em>rs1138272 C > T</em> (A114V), in CRC patients (<em>n</em> = 103) and controls (<em>n</em> = 107) of south Indian origin using PCR-sequencing analysis with genomic DNA from blood samples.
