Genes affected
NDUFA6 (HGNC:7690): (NADH:ubiquinone oxidoreductase subunit A6) This gene encodes a member of the LYR family of proteins that contain a highly conserved tripeptide (LYR) motif near the N-terminus. The encoded protein is an accessory subunit of NADH: ubiquinone oxidorerductase (Complex I), which is the largest enzyme of the mitochondrial membrane respiratory chain. Complex I functions in electron transfer from NADH to the respiratory chain. [provided by RefSeq, Oct 2016]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.392G>A (p.R131Q) alteration is located in exon 3 (coding exon 3) of the NDUFA6 gene. This alteration results from a G to A substitution at nucleotide position 392, causing the arginine (R) at amino acid position 131 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
