Invitae | RCV003798053 | SCV004579702 | likely pathogenic | Mitochondrial complex II deficiency, nuclear type 1; Paragangliomas 5 | 2023-03-07 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Studies have shown that disruption of this splice site results in skipping of exon 7 and introduces a premature termination codon (Invitae). The resulting mRNA is expected to undergo nonsense-mediated decay. This variant has not been reported in the literature in individuals affected with SDHA-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 7 of the SDHA gene. RNA analysis indicates that disruption of this splice site induces altered splicing and may result in an absent or disrupted protein product. |
