Probe mean beta values at the BRCA1 gene. a Mean beta values measured from 419 tumour-enriched DNA in our dataset. Twenty probes overlapping exon 1 of BRCA1, exon 1 of NBR2 and their shared bi-directional promoter showed increased methylation in triple-negative breast cancers (TNBC) compared with Luminal A (Lum A), Luminal B (Lum B) and HER2-positive (HER2-pos) subtypes (* denotes probes not present in the TCGA dataset). b Mean beta values measured from 156 tumour-enriched DNA in TCGA. Twenty-two probes overlapping exon 1 of BRCA1, exon 1 of NBR2 and their shared bi-directional promoter showed increased methylation in basal-like breast cancers (TNBC) compared with Luminal A (Lum A), Luminal B (Lum B) and HER2-enriched (HER2-pos) subtypes (+ denotes probes not present in our dataset)
