Of the 55-s hits, two were somatic second mutations: TSC2 NM_000548 c.774G>C in the tumor of CABR47, but presumably a passenger mutation (8% allele frequency (AF)); TP53 NM_001126112 c.365_366delTG in the tumor of CABR45, likely the driver mutation (20% AF). The gene discussed is TP53; the disease is neoplasm.
