Genes affected

ACSL3 (HGNC:3570): (acyl-CoA synthetase long chain family member 3) The protein encoded by this gene is an isozyme of the long-chain fatty-acid-coenzyme A ligase family. Although differing in substrate specificity, subcellular localization, and tissue distribution, all isozymes of this family convert free long-chain fatty acids into fatty acyl-CoA esters, and thereby play a key role in lipid biosynthesis and fatty acid degradation. This isozyme is highly expressed in brain, and preferentially utilizes myristate, arachidonate, and eicosapentaenoate as substrates. The amino acid sequence of this isozyme is 92% identical to that of rat homolog. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.1042C>T (p.R348C) alteration is located in exon 9 (coding exon 6) of the ACSL3 gene. This alteration results from a C to T substitution at nucleotide position 1042, causing the arginine (R) at amino acid position 348 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
