Genes affected

ACSL6 (HGNC:16496): (acyl-CoA synthetase long chain family member 6) The protein encoded by this gene catalyzes the formation of acyl-CoA from fatty acids, ATP, and CoA, using magnesium as a cofactor. The encoded protein plays a major role in fatty acid metabolism in the brain. Translocations with the ETV6 gene are causes of myelodysplastic syndrome with basophilia, acute myelogenous leukemia with eosinophilia, and acute eosinophilic leukemia. Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Apr 2011]

The c.1631A>G (p.Y544C) alteration is located in exon 17 (coding exon 17) of the ACSL6 gene. This alteration results from a A to G substitution at nucleotide position 1631, causing the tyrosine (Y) at amino acid position 544 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
