| Invitae | RCV001220387 | SCV001392374 | uncertain significance | Dyskeratosis congenita | 2023-12-04 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 966 of the CTC1 protein (p.Arg966Trp). This variant is present in population databases (rs200208356, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with CTC1-related conditions. ClinVar contains an entry for this variant (Variation ID: 949014). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt CTC1 protein function with a positive predictive value of 80%. 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. |
| Ambry Genetics | RCV002562504 | SCV003698876 | uncertain significance | Inborn genetic diseases | 2022-02-10 | criteria provided, single submitter | clinical testing | The c.2896C>T (p.R966W) alteration is located in exon 17 (coding exon 17) of the CTC1 gene. This alteration results from a C to T substitution at nucleotide position 2896, causing the arginine (R) at amino acid position 966 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
