Genes affected

ACSS2 (HGNC:15814): (acyl-CoA synthetase short chain family member 2) This gene encodes a cytosolic enzyme that catalyzes the activation of acetate for use in lipid synthesis and energy generation. The protein acts as a monomer and produces acetyl-CoA from acetate in a reaction that requires ATP. Expression of this gene is regulated by sterol regulatory element-binding proteins, transcription factors that activate genes required for the synthesis of cholesterol and unsaturated fatty acids. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2009]

The c.30C>G (p.S10R) alteration is located in exon 1 (coding exon 1) of the ACSS2 gene. This alteration results from a C to G substitution at nucleotide position 30, causing the serine (S) at amino acid position 10 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
