Genes affected

ACSS1 (HGNC:16091): (acyl-CoA synthetase short chain family member 1) This gene encodes a mitochondrial acetyl-CoA synthetase enzyme. A similar protein in mice plays an important role in the tricarboxylic acid cycle by catalyzing the conversion of acetate to acetyl CoA. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

Ambry Genetics

Aug 05, 2023

The c.2006G>C (p.S669T) alteration is located in exon 14 (coding exon 14) of the ACSS1 gene. This alteration results from a G to C substitution at nucleotide position 2006, causing the serine (S) at amino acid position 669 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
