RCV001932525 | SCV002133789 | pathogenic | not provided | 2023-04-14 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the KCNV2 protein in which other variant(s) (p.Leu469Trpfs*35) have been determined to be pathogenic (PMID: 18400204). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 1367585). This premature translational stop signal has been observed in individual(s) with retinal cone dystrophy (PMID: 19952985). This variant is present in population databases (rs149648640, gnomAD 0.009%). This sequence change creates a premature translational stop signal (p.Gly461*) in the KCNV2 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 85 amino acid(s) of the KCNV2 protein. |

RCV003407863 | SCV004107854 | likely pathogenic | KCNV2-related disorder | 2023-05-29 | criteria provided, single submitter | clinical testing | The KCNV2 c.1381G>T variant is predicted to result in premature protein termination (p.Gly461*). This variant has been reported along with a second KCNV2 variant in an individual with cone dystrophy (Robson et al. 2009. PubMed ID: 19952985). This variant is reported in 0.0085% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/9-2729470-G-T). Nonsense variants in KCNV2 are expected to be pathogenic. Given the evidence, we interpret c.1381G>T (p.Gly461*) as likely pathogenic. |
