Forty-six genes and other transcripts were differentially expressed in the luminal A comparison (39 increased and 7 decreased in AA tumors, Table S3D) including polycystin (PKD) family receptor for egg jelly (PKDREJ; -1.18 log2 fold-change; P = 9.56E-04) which is point mutated in breast cancer [39]. This evidence concerns the gene PRKD1 and breast cancer.
