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]

The c.1790T>G (p.V597G) alteration is located in exon 13 (coding exon 13) of the ACSS1 gene. This alteration results from a T to G substitution at nucleotide position 1790, causing the valine (V) at amino acid position 597 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
