| Invitae | RCV001224710 | SCV001396926 | uncertain significance | Dyskeratosis congenita | 2023-06-24 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 952575). This variant has not been reported in the literature in individuals affected with CTC1-related conditions. This variant is present in population databases (rs371541763, gnomAD 0.02%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 6 of the CTC1 protein (p.Ala6Val). |
| Ambry Genetics | RCV003163752 | SCV003895160 | uncertain significance | Inborn genetic diseases | 2023-01-24 | criteria provided, single submitter | clinical testing | The c.17C>T (p.A6V) alteration is located in exon 1 (coding exon 1) of the CTC1 gene. This alteration results from a C to T substitution at nucleotide position 17, causing the alanine (A) at amino acid position 6 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
