Moreover, these two SBS subtypes differed in somatic mutations in several cancer driver genes, including higher mutation frequency of ERBB2, GATA3 and FGFR4, and lower frequency of DMD, INHBA, OGDHL, PLEKHG5 and RYR2 in subtype 3 than in subtype 1 (P < 0.05; Fig. 3a). The gene discussed is ERBB2; the disease is cancer.
