In a 29-year-old woman with a rare choroid plexus papilloma (260500) who had had, at the age of 22 years, an osteosarcoma (259500), Rutherford et al. (2002) detected a germline 7-bp insertion in exon 5 of the p53 gene. The alteration was predicted to produce amino acid substitutions beginning with alanine to glycine at position 161 and a stop codon at position 182 in the mutated protein. Two assays of p53 function gave apparently wildtype results on peripheral blood lymphocytes from this woman. The mutant allele was expressed either at very low levels or not at all in phytohemagglutinin-stimulated lymphocytes. Furthermore, the mutant protein was completely nonfunctional in terms of its ability to transactivate a series of p53-responsive genes, to transrepress a target gene, and to inhibit colony growth in transfected cells. However, data from irradiated peripheral blood lymphocytes and transfected cells suggested that this truncated, mutant protein retained significant ability to induce apoptosis.
