Genes affected

ACOT2 (HGNC:18431): (acyl-CoA thioesterase 2) This gene encodes a member of the acyl-CoA thioesterase protein family, and is one of four acyl-CoA hydrolase genes located in a cluster on chromosome 14. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2012]

Collection Method: clinical testing

The c.473G>T (p.R158L) alteration is located in exon 1 (coding exon 1) of the ACOT2 gene. This alteration results from a G to T substitution at nucleotide position 473, causing the arginine (R) at amino acid position 158 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
