Pulmonary fibrosis and/or bone marrow failure syndrome, telomere-related, 9

Telomere-related pulmonary fibrosis and/or bone marrow failure syndrome-9 (PFBMFT9) is an autosomal dominant short telomere syndrome characterized by the development of pulmonary fibrosis or hematologic abnormalities, including leukopenia and leukemia, in adulthood. Liver disease may also be present. There is incomplete penetrance and evidence of genetic anticipation. Affected individuals have shortened telomeres, but do not show mucocutaneous manifestations (Kannengiesser et al., 2020). For a discussion of genetic heterogeneity of telomere-related pulmonary fibrosis and/or bone marrow failure, see PFBMFT1 (614742). [from OMIM]
