RCV001263470 | SCV001441546 | likely pathogenic | Pulmonary fibrosis and/or bone marrow failure, Telomere-related, 2 | 2020-10-29 | criteria provided, single submitter | clinical testing | TERC n.95G>C has been reported in patients presenting with aplastic anemia and dyskeratosis congenita. This variant is absent from a large population dataset and has not been reported in ClinVar. It is located within the pseudoknot/template domain, which is an important region for telomerase RNA structure. A functional study demonstrated that this variant causes significantly decreased telomerase activity compared to wild-type. We consider this variant to be likely pathogenic. |

RCV001880061 | SCV002267850 | uncertain significance | Dyskeratosis congenita, autosomal dominant 1 | 2021-01-25 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant is located within the template/pseudoknot domain of the TERC RNA component, which is required for RNA or RNP stability (PMID: 15082312, 21844345). A significant number of previously reported TERC mutations are found in this domain (PMID: 15082312, 21844345, 21931702). These observations suggest that this may be a clinically significant region of the protein. Studies have shown that this variant alters TERC gene expression (PMID: 26024875). This variant has been observed in individual(s) with dyskeratosis congenita (DC) (PMID: 26024875). ClinVar contains an entry for this variant (Variation ID: 983511). This variant is not present in population databases (ExAC no frequency). This variant occurs in the TERC gene, which encodes an RNA molecule that does not result in a protein product. |
