Pulmonary fibrosis is the most common short telomere manifestation. (A) Typical appearance of telomere-related IPF characterized on CT by honeycombing in the lung bases. (B) Schematic showing progressive neutropenia after lung transplant that improved after immunosuppressant regimen was attenuated. (C) Lymphocyte telomere length by flow cytometry and fluorescence in situ hybridization (flowFISH) in representative case.
