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]

Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Nov 22, 2023	The ACSF3 c.1406G>A; p.Arg469Gln variant (rs144681140), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 203601). This variant is found in the general population with an overall allele frequency of 0.45% (1271/282590 alleles, including 3 homozygotes) in the Genome Aggregation Database. The arginine at codon 469 is weakly conserved, and computational analyses predict that this variant is neutral (REVEL: 0.114). While the high population frequency suggests that this is likely a benign variant, given the lack of clinical and functional data, the significance of this variant is uncertain at this time. -

The R469Q variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to ourknowledge. The R469Q variant is observed in 425/66442 (0.64%) alleles from individuals of European backgroundincluding one homozygote (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). TheR469Q variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as theseresidues differ in some properties. This substitution occurs at a position that is not conserved. In silico analysis isinconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Insummary, based on the currently available information, it is unclear whether this variant is a pathogenic variant or arare benign variant. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
