Furthermore, messenger ribonucleic acid (mRNA) expression and splicing information obtained from the GTEx portal database (https://gtexportal.org/home/, accessed on 18 June 2022) demonstrated, firstly, that 10 BC risk loci and 115 SNPs among 124 loci strongly linked to them (92.74%) are identified by eQTL for 23 genes, such as RP11-212I21.2, RP11-465L10.10, RP11-817J15.3, RP3-337O18.9, RPL13P2, CD40, DNTTIP1, MMP1, MMP10, PCIF1, NEURL2, MP27, MMP9, PLTP, SLC12A5, SNX21, SPATA25, SYS1, WFDC10B, WFDC3, WTAPP1, ZNF335, and ZSWIM1 (Supplementary Tables S7 and S8). This evidence concerns the gene RPL13P2 and breast cancer.
