Notably, 31% of the genes harboring SNPs associated with CRC risk (20 of 63) were related to selenoprotein biosynthesis and function implicated in protection from cancer development [4,21] with pathway 1 and 2 proteins involved in (1) Se homeostasis (SELENOP, SEPHS1, SEPSEC, EFSEC, SCLY), (2) antioxidant enzymes (GPXs, TXNRDs, SELENON), and (3) endoplasmic reticulum (ER) function or stress (SELENOF, SELENOM, SELENOT, and again SELENON). The gene discussed is EEFSEC; the disease is colorectal carcinoma.
