Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251324 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.827G>A has been reported in the literature in individuals affected with Leber hereditary optic neuropathy and unspecified mitochondrial disease (examples: Mansukhani_2021 and Schon_2021). These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 32918965, 34732400). No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. (less)
