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]

Ambry Genetics

Jan 04, 2024

The c.281C>T (p.A94V) alteration is located in exon 4 (coding exon 4) of the NDUFA7 gene. This alteration results from a C to T substitution at nucleotide position 281, causing the alanine (A) at amino acid position 94 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
