Genes affected

NDUFAF7 (HGNC:28816): (NADH:ubiquinone oxidoreductase complex assembly factor 7) This gene encodes an assembly factor protein which helps in the assembly and stabilization of Complex I, a large multi-subunit enzyme in the mitochondrial respiratory chain. Complex I is involved in several physiological activities in the cell, including metabolite transport and ATP synthesis. The encoded protein is a methyltransferase which methylates Arg85 of a subunit of Complex I in the early stages of its assembly. A pseudogene related to this gene is located on chromosome 8. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2016]

NDUFAF7 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.01).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.76 is higher than 0.05.
