• rs1244209138
• NM_001394565.1:c.64C>G

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_001394565.1(ATPAF1):​c.64C>G​(p.Leu22Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000664 in 150,572 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. L22F) has been classified as Uncertain significance.

Genes affected

ATPAF1 (HGNC:18803): (ATP synthase mitochondrial F1 complex assembly factor 1) This gene encodes an assembly factor for the F(1) component of the mitochondrial ATP synthase. This protein binds specifically to the F1 beta subunit and is thought to prevent this subunit from forming nonproductive homooligomers during enzyme assembly. Alternatively spliced transcript variants have been identified. [provided by RefSeq, Aug 2011]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
