Labcorp Genetics (formerly Invitae), Labcorp RCV003043796 SCV003341113 uncertain significance Gastrointestinal stromal tumor; Paragangliomas 3 2022-04-12 criteria provided, single submitter clinical testing This sequence change affects an acceptor splice site in intron 5 of the SDHC 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. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SDHC-related conditions. 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. 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.
