Genes affected

NDUFS8 (HGNC:7715): (NADH:ubiquinone oxidoreductase core subunit S8) This gene encodes a subunit of mitochondrial NADH:ubiquinone oxidoreductase, or Complex I, a multimeric enzyme of the respiratory chain responsible for NADH oxidation, ubiquinone reduction, and the ejection of protons from mitochondria. The encoded protein is involved in the binding of two of the six to eight iron-sulfur clusters of Complex I and, as such, is required in the electron transfer process. Mutations in this gene have been associated with Leigh syndrome. [provided by RefSeq, Mar 2010]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 11 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.74371 (below the threshold of 3.09). Trascript score misZ: 1.1202 (below the threshold of 3.09). GenCC associations: The gene is linked to Leigh syndrome, Leigh syndrome with leukodystrophy, mitochondrial complex I deficiency, nuclear type 2, mitochondrial complex I deficiency.

BP4

Computational evidence support a benign effect (MetaRNN=0.17939991).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000698 (102/1460640) while in subpopulation SAS AF = 0.000893 (77/86194). AF 95% confidence interval is 0.000732. There are 0 homozygotes in GnomAdExome4. There are 76 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
