The variant allele was found at a frequency of 0.6 in 151,976 control chromosomes in the GnomAD database, including 27,435 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.60 (27435 hom., cov: 32)
• Consequence: ACAA2 NM_006111.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.163

Genes affected

ACAA2 (HGNC:83): (acetyl-CoA acyltransferase 2) The encoded protein catalyzes the last step of the mitochondrial fatty acid beta-oxidation spiral. Unlike most mitochondrial matrix proteins, it contains a non-cleavable amino-terminal targeting signal. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.634 is higher than 0.05.
