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]

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.66).
• BP7: Synonymous conserved (PhyloP=-1.33 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.251 is higher than 0.05.
