DNA methylation at the VTRNA2-1 promoter. a Genomic locations of 6 HM450K probes associated with VTRNA2-1 promoter region. b DNA methylation levels (β-values) of these 6 probes labelled by breast cancer status. β-values for each individual are shown on y axis for 6 VTRNA2-1 probes. c Average DNA methylation levels across all six probes shown separately for individual families and labelled by breast cancer status. β-values are shown on y axis for members from each family (y axis)
