MUC4 and neoplasm: Still, for the majority of pairs (6 of 7), the somatic MUC4 SNV was predicted at the same genomic position, in 5 of the 6 pairs, either the initial or the recurrent tumor also showed additional private somatic MUC4 SNVs at other locations with a tendency that recurrent tumors had more additional private MUC4 mutations (recurrent: three additional SNVs in P08-G4 and P05-G4, initial: one additional SNV in P07-A3, P12-A3, and P13-A3).
