However, Mikeska et al (2013) found little evidence of PALB2 methylation in high-grade serous ovarian cancer using a methylation-sensitive high-resolution melting assay, and Poumpouridou et al (2016) were unable to detect PALB2 promoter methylation in a series of 91 breast cancers [10,11]. This evidence concerns the gene PALB2 and breast carcinoma.
