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]

NDUFA7 links:

RPS28 (HGNC:10418): (ribosomal protein S28) Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 40S subunit. The protein belongs to the S28E family of ribosomal proteins. It is located in the cytoplasm. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Jul 2008]

Feb 21, 2024

The c.22A>G (p.I8V) alteration is located in exon 1 (coding exon 1) of the NDUFA7 gene. This alteration results from a A to G substitution at nucleotide position 22, causing the isoleucine (I) at amino acid position 8 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
