Genes affected

CES1 (HGNC:1863): (carboxylesterase 1) This gene encodes a member of the carboxylesterase large family. The family members are responsible for the hydrolysis or transesterification of various xenobiotics, such as cocaine and heroin, and endogenous substrates with ester, thioester, or amide bonds. They may participate in fatty acyl and cholesterol ester metabolism, and may play a role in the blood-brain barrier system. This enzyme is the major liver enzyme and functions in liver drug clearance. Mutations of this gene cause carboxylesterase 1 deficiency. Three transcript variants encoding three different isoforms have been found for this gene. [provided by RefSeq, Jun 2010]

The c.1303C>G (p.R435G) alteration is located in exon 11 (coding exon 11) of the CES1 gene. This alteration results from a C to G substitution at nucleotide position 1303, causing the arginine (R) at amino acid position 435 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
