In this study, we have identified a few commonly mutated genes in pre-NACT tumor samples from either sensitive (DNAH5, CYP2D6, NUTM1) or resistant (CSPG4, TUBA3D, SLC35G5) cases, which suggest that these genes could have a potential utility for prediction of the response to NACT. This evidence concerns the gene CSPG4 and neoplasm.
