A disease associated with shortened telomeres. Pulmonary fibrosis is the most common manifestation. Other manifestations include aplastic anemia due to bone marrow failure, hepatic fibrosis, and increased cancer risk, particularly myelodysplastic syndrome and acute myeloid leukemia.

The disease is pulmonary fibrosis, and/or bone marrow failure, telomere-related, 5 (EFO_0010664, an Experimental Factor Ontology identifier).
