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 made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.76).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00061 (93/152410) while in subpopulation AFR AF= 0.00207 (86/41602). AF 95% confidence interval is 0.00171. There are 0 homozygotes in gnomad4. There are 50 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
