Genes affected
ACSL1 (HGNC:3569): (acyl-CoA synthetase long chain family member 1) 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. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.2044C>T (p.R682W) alteration is located in exon 21 (coding exon 20) of the ACSL1 gene. This alteration results from a C to T substitution at nucleotide position 2044, causing the arginine (R) at amino acid position 682 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
