Genes affected

NDUFA10 (HGNC:7684): (NADH:ubiquinone oxidoreductase subunit A10) The protein encoded by this gene is a component of 42 kDa complex I, the first enzyme complex in the electron transport chain of mitochondria. This protein has NADH dehydrogenase activity and oxidoreductase activity. It transfers electrons from NADH to the respiratory chain. A mutation in this gene was found in an individual with Leigh syndrome. [provided by RefSeq, Apr 2016]

Variant summary: NDUFA10 c.1A>G (p.Met1?, aka p.Met1Val) alters the initiation codon and is predicted to result either in absence of the protein or truncation/extension of the encoded protein due to translation initiation at a downstream/upstream codon. No upstream in-frame ATG triplets were found that could generate an N-terminally extended protein product, and although a downstream in-frame ATG triplet was found, (i.e. Met40 in Exon 2), the utilization of Met40 as a start codon would result in an N-terminally truncated protein product, with the loss of the mitochondrial targeting signal (i.e. the 35 N-terminal amino acids; see Dang_2020). The variant allele was found at a frequency of 2.9e-05 in 103762 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. The variant, c.1A>G, has been reported in the literature in a compound heterozygous individual affected with Mitochondrial Complex 1 Deficiency, Nuclear Type 22 (Hoefs_2011), and the authors of this study described a marked decrease of complex I activity in patient derived fibroblasts and muscle tissue, together with a strongly decreased NDUFA10 protein level on Western blot analysis. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic. -
