Haploinsufficiency of t e lomerase reverse transcriptase leads to anticipation in autosomal dominant dyskeratosis congenita
Open accessAbstract
Dyskeratosis congenita is a rare inherited disorder characterized by abnormal skin manifestations. Morbidity and mortality from this disease is usually due to bone marrow failure, but idiopathic pulmonary fibrosis and an increased cancer predisposition also occur. Families with autosomal dominant dyskeratosis congenita display anticipation and have mutations in the telomerase RNA gene. We identified a three-generation pedigree with autosomal dominant dyskeratosis congenita, anticipation, and telomere shortening. We show that a null mutation in motif D of the reverse transcriptase domain of the protein component of telomerase, hTERT, is associated with this phenotype. This mutation leads to haploinsufficiency of telomerase, and telomere shortening occurs despite the presence of telomerase. This finding emphasizes the importance of telomere maintenance and telomerase dosage for maintaining tissue proliferative capacity and has relevance for understanding mechanisms of age-related changes.

“They manifest in an autosomal-dominant inheritance pattern because complete or partial loss-of-function of one allele is sufficient to perturb telomere maintenance38,39,41.”
From The telomere syndromes (2012) · cites this paper as [39]
In the citing paper
“The most compelling evidence for the causal role of telomere shortening as a primary modifier of disease is that families with mutant telomerase genes display genetic anticipation39,83.”
From The telomere syndromes (2012) · cites this paper as [39]
In the citing paper
“Eight mutant genes have been identified in dyskeratosis congenita9,38,39,60–64, and all of them encode telomerase or telomere protein components (summarized in Table 1).”

“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.”

From The telomere syndromes (2012) · cites this paper as [39]
In the citing paper
“Among the genes we evaluated was TERT, which was considered a candidate because a mutation in this gene was recently reported to cause autosomal dominant dyskeratosis congenita (DKC), a disorder in which 20% of affected individuals develop pulmonary fibrosis (6, 7).”
From Adult-onset pulmonary fibrosis caused by mutations in telomerase (2007) · cites this paper as [6]
In the citing paper
“Telomere length is influenced by many different factors, including age (13, 14) and the number of generations the mutation is transmitted (6, 15).”
From Adult-onset pulmonary fibrosis caused by mutations in telomerase (2007) · cites this paper as [6]
In the citing paper
“The individuals with TERT or TERC mutations have none of the physical manifestations of DKC and were all ascertained by the lung fibrosis phenotype, distinguishing them from previously described patients with mutations in these genes (6, 9, 10, 17).”

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.
