Labcorp Genetics (formerly Invitae), Labcorp RCV003708808 SCV004484767 pathogenic not provided 2023-01-17 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the NDUFS6 protein in which other variant(s) (p.Cys115Arg) have been determined to be pathogenic (PMID: 28429146, 30948790, 31967322). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant has not been reported in the literature in individuals affected with NDUFS6-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 3 of the NDUFS6 gene. While this variant is not anticipated to result in nonsense mediated decay, it likely alters RNA splicing and results in a disrupted protein product.
