Genes affected

NDUFA7 (HGNC:7691): (NADH:ubiquinone oxidoreductase subunit A7) This gene encodes a subunit of NADH:ubiquinone oxidoreductase (complex I), which is a multiprotein complex located in the inner mitochondrial membrane. Complex I functions in the transfer of electrons from NADH to the respiratory chain. [provided by RefSeq, Mar 2011]

The c.158A>G (p.Y53C) alteration is located in exon 3 (coding exon 3) of the NDUFA7 gene. This alteration results from a A to G substitution at nucleotide position 158, causing the tyrosine (Y) at amino acid position 53 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
