Germline p53 mutations are associated with Li-Fraumeni syndrome (LFS) and other familial cancer phenotypes not fulfilling the definition for LFS. The majority of germline p53 mutations cluster in exons 5-8, corresponding to a DNA binding domain. We report the identification of two germline mutations and a somatic mutation in a tetramerization domain (TD), a rare site for mutations. The germline mutation, R342X (16915C>T), and the novel mutation, R342P (16916G>C), were found in a child with adrenocortical carcinoma and in a LFS pediatric patient with multiple primaries. The novel somatic mutation, R337G (16900C>G), was discovered in myelodysplastic syndrome with transformation to acute myeloblastic leukemia, developing as the third primary in the LFS child. These findings add further information on p53 TD mutations and TD contribution to tumorigenesis.

Myelodysplastic syndromes and acute myeloid leukemia are sporadic for the majority of cases affecting the elderly population. Inherited cases, however, do occur. Genetic predispositions to myeloid malignancies can be classified into three categories: familial cancer syndromes associated with increased risk of various malignancies including myelodysplasia and acute myeloid leukemia such as Li-Fraumeni syndrome and constitutional mismatch repair deficiency (CMMRD); germline mutations conferring a specific increased risk of myelodysplastic syndrome and acute myeloid leukemia such as mutations in ANKRD26, CEBPA, DDX41, ETV6, GATA2, RUNX1, SRP72 genes; and finally primarily pediatric inherited bone marrow failure syndromes such as Fanconi anemia, dyskeratosis congenita, severe congenital neutropenia, Shwachman-Diamond syndrome and Diamond Blackfan anemia. The recognition of these germline syndromes is essential in the management and follow-up of patients. Herein, we review the conditions associated with hereditary myeloid leukemia with a special clinical focus on management and monitoring.
