Using whole exome sequencing data obtained from 1,685 Japanese cancer patients, we examined genetic variations of germline TP53 and found 10 types of non-synonymous single nucleotide variants. In the present study, we focused on 6 patients with germline D49H mutation located in the transactivation domain 2 of p53 protein, since the mutation seemed to be prevalent in cancer patients and to be pathogenic. According to the initial survey for family history of the proband with the germline TP53 D49H mutation, one osteosarcoma patient and his pedigree fulfill the criteria for Li-Fraumeni-like syndrome and the 2009 Chompret criteria for germline TP53 mutation screening. Since this patient possesses double germline mutations of TP53 D49H and A159D, further studies are required to evaluate contribution of the D49H mutation in this morbidity. The remaining 5 patients had family histories of cancer, but none fulfills the criteria either for the Li-Fraumeni/Li-Fraumeni-like syndromes or the 2009 Chompret criteria for germline TP53 mutation screening. It is possible to postulate that the germline TP53 D49H mutation is likely to be low-penetrant in some pedigrees. The present study also indicates that the survey for the germline TP53 mutation plays an important role in clinical practice as it will prevent mistaking cancer patients with unusual heredities for sporadic cases.
