Violin plots representing log-scaled allele-specific expression of classical and non-classical HLA loci and B2M protein in two breast cancer subtypes (in green for ER + /HER2- and blue for TNBC subtypes) and normal adjacent tissues (in gray). A ER + /HER2- primary tumor vs. matched normal adjacent tissue. B TNBC primary tumor vs. matched normal adjacent tissue. The dotted lines represent the quartile positions. * P-value < 0.05, ** P-value < 0.01
