Furthermore, the mQTL rs13447450 of CpG site cg03260624 and rs70953670 of CpG site cg26312998 are strong eQTLs of the CDC7 gene and the ZNF318 gene in breast mammary tissue, respectively, indicating that the effect of changed methylation at cg03260624 and cg26312998 on breast cancer might be mediated by gene expression. This evidence concerns the gene CDC7 and breast carcinoma.
