GRIK1 and cancer: However, nine of these genes (i.e., KHDRBS3, PRKG1, ZRANB1, THRB, FSTL4, HTR1E, LINC01377, MIR4675, and GRIK1) were previously implicated in cancers at other sites (i.e., other than those in our study) at PGWAS < 5.0 ×10−6 [34,35], and 7 genes (i.e., SNX31, KHDRBS3, GLRX3, THRB, MAP7, ATP8B1, and GRIK1) were prognostically linked to other cancers at P < 0.001 (The Human Protein Atlas [60]: www.proteinatlas.org accessed on 2019–2020) (Table 1).
