Adult-onset pulmonary fibrosis caused by mutations in telomerase
Open accessAbstract
Idiopathic pulmonary fibrosis (IPF) is an adult-onset, lethal, scarring lung disease of unknown etiology. Some individuals with IPF have a familial disorder that segregates as a dominant trait with incomplete penetrance. Here we used linkage to map the disease gene in two families to chromosome 5. Sequencing a candidate gene within the interval, TERT , revealed a missense mutation and a frameshift mutation that cosegregated with pulmonary disease in the two families. TERT encodes telomerase reverse transcriptase, which together with the RNA component of telomerase ( TERC ), is required to maintain telomere integrity. Sequencing the probands of 44 additional unrelated families and 44 sporadic cases of interstitial lung disease revealed five other mutations in TERT . A heterozygous mutation in TERC also was found in one family. Heterozygous carriers of all of the mutations in TERT or TERC had shorter telomeres than age-matched family members without the mutations. Thus, mutations in TERT or TERC that result in telomere shortening over time confer a dramatic increase in susceptibility to adult-onset IPF.

Written from the paper’s full text.
TL;DR
Mutations in *TERT* or *TERC* that cause telomere shortening confer susceptibility to adult-onset idiopathic pulmonary fibrosis (IPF). The study links telomerase dysfunction to familial and sporadic IPF, with incomplete penetrance and possible smoking exacerbation.
Key findings
- Linkage in two large families mapped disease to chromosome 5p15 with a maximal LOD score of 2.8; sequencing the candidate gene *TERT* found a missense mutation (R865H) and a frameshift mutation (V747fsX766) that cosegregated with pulmonary disease.
- In 44 additional unrelated familial interstitial lung disease probands and 44 sporadic cases, five other *TERT* mutations were found (total: two frameshift deletions and five missense mutations), plus one heterozygous *TERC* mutation (r.37a>g); none of the seven *TERT* mutations were found in 94 ethnically matched controls, 200 patients with aplastic anemia, or a multiethnic panel of 528 controls.
- Heterozygous carriers of *TERT* or *TERC* mutations had shorter telomeres than age-matched family members without the mutations; in vitro TRAP assays showed frameshift mutants had little detectable telomerase activity, missense and *TERC* mutants ranged from zero to 100% of wild-type activity, and mixing V747fs with wild-type *TERT* suggested haploinsufficiency.
- Among mutation carriers, smokers died at an average age of 58 years (n = 13) versus 68 years for nonsmokers (n = 7); all affected individuals developed pulmonary fibrosis in adulthood with no history of pediatric lung disease.
Methods
- Clinical sample: 46 families with two or more cases of idiopathic interstitial lung disease (34 of 46 families had individuals with IPF) and 44 sporadic interstitial lung disease cases (31 with IPF); genomic DNA was isolated from leukocytes, and for four individuals from formalin-fixed paraffin-embedded archival samples.
- Linkage analysis: whole-genome SNP genotyping with the Illumina Linkage IVb panel of >6,000 polymorphic SNPs; MERLIN was used for multipoint model-free and model-based linkage analysis, with the highest peak on chromosome 5p15.
- Mutation and functional analysis: *TERT* exons and splice sites and 451 bp encoding *TERC* were sequenced; telomerase activity was measured by the TRAP assay using in vitro coexpressed recombinant protein and RNA; telomere length was assessed by terminal restriction fragment (TRF) Southern blot analysis of leukocyte DNA.
Limitations
- The paper does not include a formal limitations section; it states that pulmonary fibrosis appears to be a human-specific manifestation of telomerase deficiency and that it is not yet reported whether aged telomerase-deficient mice develop similar lung pathology.
- The paper notes incomplete penetrance: some family members who inherited a *TERT* mutation had no evidence of pulmonary disease, and environmental influences such as cigarette smoking may affect the phenotype.
- Evident from the text: linkage mapping relied on two families, mutation screening focused on the candidate genes *TERT* and *TERC*, and in vitro TRAP activity did not always track telomere shortening because some mutations caused telomere shortening without a detectable decrease in telomerase activity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
