Telomerase Reverse Transcriptase (TERT) encodes the telomerase reverse transcriptase enzyme and is the most frequently mutated gene in patients with telomeropathies. Heterozygous variants impair telomerase activity by haploinsufficiency and pathogenic variants are associated with bone marrow failure syndrome and predisposition to acute myeloid leukaemia. Owing to their rarity, telomeropathies are often unrecognised and misdiagnosed. Herein, we report a novel TERT gene variant, c.2605G > A p.(Asp869Asn) in a family with hereditary aplastic anaemia. This report emphasises the importance of routine deep genetic screening for rare TERT variants in patients with a family history of cytopenia or aplastic anaemia, which could identify clinically inapparent telomere disorders. © The Author(s), under exclusive licence to Springer Nature B.V. 2024.
