This variant occurs in the TERC gene, which encodes an RNA molecule that does not result in a protein product. This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with TERC-related conditions. ClinVar contains an entry for this variant (Variation ID: 935195). 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). 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. -
