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]

ENSG00000306411 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.01578024).
• BP6: Variant 20-25013978-C-T is Benign according to our data. Variant chr20-25013978-C-T is described in ClinVar as Benign. ClinVar VariationId is 1258805.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAdExome4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0536 is higher than 0.05.
