Department of Pediatrics,Hirosaki University Graduate School of Medicine RCV000677306 SCV000786666 pathogenic Diamond-Blackfan anemia 2018-05-14 no assertion criteria provided research The heterozygous protein-truncating mutations in TP53 (c.1077delA, p.Ser362AlafsX8) was detected in a patient presented with congenital hypoplastic anemia, hypogammaglobulinemia, growth retardation, microcephally and mental retardation. The variant resulted in the loss of 32 residues from the C-terminal domain (CTD). Luciferase assay using the promoter of CDKN1A showed the p53 mutant had augmented transcriptional activities. When expressed in zebrafish and human-induced pluripotent stem cells, we observed impaired erythrocyte production. The patient shared several phenotypes with the knock-in mice expressing CTD-truncated p53, including bone marrow failure, microcephaly and severe growth retardation (Simeonova 2013, Hamard 2013). These findings demonstrate that the CTD-truncation mutations of TP53 cause a novel inherited bone marrow failure syndrome.
