Genes affected

ACSF3 (HGNC:27288): (acyl-CoA synthetase family member 3) This gene encodes a member of the acyl-CoA synthetase family of enzymes that activate fatty acids by catalyzing the formation of a thioester linkage between fatty acids and coenzyme A. The encoded protein is localized to mitochondria, has high specificity for malonate and methylmalonate and possesses malonyl-CoA synthetase activity. Mutations in this gene are a cause of combined malonic and methylmalonic aciduria. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Sep 2013]

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 16, 2023	This sequence change creates a premature translational stop signal (p.Arg523*) in the ACSF3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ACSF3 are known to be pathogenic (PMID: 21841779, 26827111). This variant is present in population databases (rs387907118, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with combined malonic and methylmalonic aciduria (PMID: 21841779). ClinVar contains an entry for this variant (Variation ID: 31135). For these reasons, this variant has been classified as Pathogenic. -
