The top autosomal DNAm sites were mapped to genes that have been associated with breast cancer and other malignancies (e.g., cg02325951 on FOXN3, cg20262915 and cg19765154 on NAB1, and cg07850329 on BAG1) [52–54], as well as childhood neurodegeneration (e.g., cg12607525 on UBTF) [55] (Additional file 2: Table S3). Here, NAB1 is linked to breast cancer.
