A total of six strongly associated SNPs with breast cancer in the European population dataset ebi-a-GCST90018799 were selected from the following mitochondrial-related components: prot-a-1943 (39S ribosomal protein L34), prot-a-2190 (pyruvate carboxylase), prot-a-641 (cytochrome c oxidase subunit 8A), prot-a-2129 (ADP-ribose pyrophosphatase), prot-a-2575 (rRNA methyltransferase 3), and prot-a-612 (cytochrome c oxidase assembly factor 3 homolog) (Figure 2(a) and Table 2). Here, COX8A is linked to breast cancer.
