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.1547G>T (p.R516L) alteration is located in exon 10 (coding exon 10) of the ACSS1 gene. This alteration results from a G to T substitution at nucleotide position 1547, causing the arginine (R) at amino acid position 516 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
