Syndromes of Telomere Shortening

Abstract

Telomeres and telomerase were initially discovered in pursuit of questions about how the ends of chromosomes are maintained. The implications of these discoveries to age-related disease have emerged in recent years with the recognition of a group of telomere-mediated syndromes. Telomere-mediated disease was initially identified in the context of dyskeratosis congenita, a rare syndrome of premature aging. More recently, mutations in telomerase components were identified in adults with idiopathic pulmonary fibrosis. These findings have revealed that the spectrum of telomere-mediated disease is broad and includes clinical presentations in both children and adults. We have previously proposed that these disorders be collectively considered as syndromes of telomere shortening. Here, the spectrum of these disorders and the unique telomere genetics that underlies them are reviewed. I also propose broader clinical criteria for defining telomere-mediated syndromes outside of dyskeratosis congenita, with the goal of facilitating their diagnosis and highlighting their pathophysiology.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • TERT interacts with the RNA component of mitochondrial RNA processing endoribonuclease and ribonuclease P and can act as an RNA-dependent RNA polymerase.

    “In addition, TERT was shown to interact with RNA component of mitochondrial RNA processing endoribonuclease, the RNA component of ribonuclease P, and in this context TERT is able to act as an RNA-dependent RNA polymerase.”

    From Telomeres and telomerase in cancer (2010) · cites this paper as [153]

  • TERT may amplify small non-coding RNAs and exert other activities through this mechanism.

    “These findings suggest that TERT may amplify small non-coding RNAs and exert other activities through this mechanism (153).”

  • The clinically diverse telomere disorders together constitute one syndrome spectrum whose defining feature is short telomere length.

    “Although these disorders seem to be clinically diverse, collectively they comprise a single syndrome spectrum defined by the short telomere defect.”

    From The telomere syndromes (2012) · cites this paper as [13]

  • Most telomere disorders appear in adulthood and result from inherited loss-of-function mutations in TERT or TR.

    “Telomere disorders most commonly manifest as adult-onset disease and as a consequence of germline TERT or TR loss-of-function mutations13.”

    From The telomere syndromes (2012) · cites this paper as [13]

  • When IPF, bone marrow failure, and liver cirrhosis occur together, this combination is specific for and strongly predicts an inherited telomere maintenance defect.

    “Indeed, the co-occurrence of IPF and bone marrow failure, along with liver cirrhosis, is specific to and highly predictive of a germline telomere maintenance defect13,39,71.”

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.

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.
