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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 11, 2024The c.143T>C (p.M48T) alteration is located in exon 2 (coding exon 2) of the NDUFAF7 gene. This alteration results from a T to C substitution at nucleotide position 143, causing the methionine (M) at amino acid position 48 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
