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_pathogenic. The variant received 7 ACMG points.

PM1

In a domain 4Fe-4S ferredoxin-type 1 (size 29) in uniprot entity NDUS8_HUMAN there are 5 pathogenic changes around while only 0 benign (100%) in NM_002496.4

PM2

Very rare variant in population databases, with high coverage;

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.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.781

PP5

Variant 11-68033254-A-G is Pathogenic according to our data. Variant chr11-68033254-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 216970.
