Genes affected

CES2 (HGNC:1864): (carboxylesterase 2) 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. The protein encoded by this gene is the major intestinal enzyme and functions in intestine drug clearance. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Oct 2010]

The c.571A>G (p.S191G) alteration is located in exon 3 (coding exon 3) of the CES2 gene. This alteration results from a A to G substitution at nucleotide position 571, causing the serine (S) at amino acid position 191 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
