TP53 and neoplasm: Forty-eight tumors had missense mutations, 23 tumors had truncational mutations, nine tumors had truncational mutations and missense mutations at the same time, five tumors had missense mutations and deletions at the same time, two tumors had missense mutations on both alleles, two tumors had truncational mutations on both alleles, and one tumor probably had a heterozygous TP53 deletion (and wild type p53 immunoexpression).
