Labcorp Genetics (formerly Invitae), Labcorp	RCV000790658	SCV001588982	pathogenic	not provided	2023-12-29	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Leu1056Profs*11) in the CACNA1F gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CACNA1F are known to be pathogenic (PMID: 9662399, 11281458, 17525176, 22194652, 24124559, 26992781). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with X-linked congenital stationary night blindness (PMID: 9662399, 9662400, 10900517). It is commonly reported in individuals of Mennonite ancestry (PMID: 9662399, 9662400, 10900517). This variant is also known as 3133inC, Leu991insC, and Leu1056insC. ClinVar contains an entry for this variant (Variation ID: 21443). For these reasons, this variant has been classified as Pathogenic.

PreventionGenetics, part of Exact Sciences	RCV003398551	SCV004121492	pathogenic	CACNA1F-related disorder	2023-05-02	criteria provided, single submitter	clinical testing	The CACNA1F c.3166dupC variant is predicted to result in a frameshift and premature protein termination (p.Leu1056Profs*11). This variant has been reported in multiple individuals with congenital stationary night blindness (see for example Vincent and Héon et al. 2012. PubMed ID: 22744390; reported as c.3133insC in Strom et al. 1998. PubMed ID: 9662399). Frameshift variants in CACNA1F are expected to be pathogenic and this variant has been classified as pathogenic by multiple independent submitters to the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/21443). Given all the evidence, we interpret c.3166dup (p.Leu1056Profs*11) as pathogenic.
