dbSNP rs3210083: NDUFA9:p.Arg360Ser (chr12-4687052-C-A) – ACMG Classification: Uncertain_significance (4 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PM5

The NM_005002.5(NDUFA9):c.1078C>A(p.Arg360Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,461,872 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R360C) has been classified as Likely pathogenic.

Genes affected

NDUFA9 (HGNC:7693): (NADH:ubiquinone oxidoreductase subunit A9) The encoded protein is a subunit of the hydrophobic protein fraction of the NADH:ubiquinone oxidoreductase (complex I), the first enzyme complex in the electron transport chain located in the inner mitochondrial membrane. A pseudogene has been identified on chromosome 12. [provided by RefSeq, May 2010]
