Genes affected

ACAT2 (HGNC:94): (acetyl-CoA acetyltransferase 2) The product of this gene is an enzyme involved in lipid metabolism, and it encodes cytosolic acetoacetyl-CoA thiolase. This gene shows complementary overlapping with the 3-prime region of the TCP1 gene in both mouse and human. These genes are encoded on opposite strands of DNA, as well as in opposite transcriptional orientation. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2014]

Collection Method: clinical testing

The c.65A>G (p.N22S) alteration is located in exon 2 (coding exon 2) of the ACAT2 gene. This alteration results from a A to G substitution at nucleotide position 65, causing the asparagine (N) at amino acid position 22 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
