Invitae RCV000536643 SCV000651410 uncertain significance Mitochondrial complex II deficiency, nuclear type 1; Paragangliomas 5 2019-11-11 criteria provided, single submitter clinical testing In summary, this is a novel silent change with uncertain impact on splicing. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with an SDHA-related disease. This sequence change affects codon 598 of the SDHA mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the SDHA protein. This variant also falls at the last nucleotide of exon 13 of the SDHA coding sequence, which is part of the consensus splice site for this exon.
