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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.1360G>A (p.A454T) alteration is located in exon 9 (coding exon 9) of the ACSS1 gene. This alteration results from a G to A substitution at nucleotide position 1360, causing the alanine (A) at amino acid position 454 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
