Region of the BRCA1 promoter (bisulfite converted) covered by the MSP assay performed by Al-Moghrabi et al. [1] and the qPCR assay performed by Lønning et al. [2]. CpG dinucleotides (potential methylation sites) are highlighted in yellow and “Y” indicates that the C in CpG could be either C or T after bisulfite conversion. Primers used in both assays are highlighted by gray background. The additional probe used by Lønning et al. is highlighted by green background and red font
