N4BP1 and nasopharyngeal carcinoma: Although recurring mutation (same mutation in multiple samples) was not observed in our analysis of 10 NPC exomes, 6 genes were found to be commonly mutated in multiple samples, i.e. CXorf22 (p.H235Y, p.A940T), MYH1 (p.A338T, p.R109C), N4BP1 (p.G685E, p.R597X), WDR87 (p.D2021E, p.M1261I), TRAF3 (p.R163X, p.S9fs), and KCNN3 (p.P81delinsQQQQQP, p.L66H).
