TP53 and neoplasm: Tumor DNA analysis revealed (a) a genomic amplification of IL-6 with an unknown effect on protein function, (b) a genomic amplification of EGFR, (c) a stop codon leading to a possible loss of function of protein KT2MD (p.R2645*), and (d) a V173L TP53 variant associated with loss of function of the corresponding protein.
