  1. TERTp pathogenic TERT.
  2. In this study, we screened 136 patients with telomeropathies that presented dyskeratosis congenita (DC, n = 21), aplastic anemia (AA, n = 86), idiopathic pulmonary fibrosis (IPF, n = 18), and other phenotypes that included myelodysplastic syndrome (MDS) or hypoplastic MDS (HypoMDS, n = 7), isolated thrombocytopenia (n = 3), and thrombocythemia (n = 1).
  3. aControl group was composed of patients with acquired AA (n = 70; median age = 28 years), IPF (n = 12; median age = 62 years), other inherited bone marrow failure syndromes (IBMFS; Diamond–Blackfan anemia, n = 4; chronic neutropenia, n = 3), and acute myeloid leukemia (AML, n = 106; Supplementary Tables S2–S3).
