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]

Variant summary: ACSF3 c.593T>G (p.Met198Arg) results in a non-conservative amino acid change located in the AMP-dependent synthetase/ligase domain (IPR000873) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 224322 control chromosomes (gnomAD). c.593T>G has been reported in the literature in two homozygous individuals affected with Combined Malonic And Methylmalonic Aciduria (Sloan_2011, Kuster_2018). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 28924877, 21841779). ClinVar contains an entry for this variant (Variation ID: 31141). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
