When comparing our results with the Swedish cohort [16], some of the top mutated genes identified in the Swedish BC cohort had similar prevalence in the Hungarian tumor samples (PIK3CA—26%,) but many of them were mutated more frequently (TP53—38%, KMT2C—32%, MUC17—29%, NEB—15%, GOLGB1—15%). This evidence concerns the gene MUC17 and neoplasm.
