[hide] Genetic variations of the ABCC2 gene in the Chines... Drug Metab Pharmacokinet. 2008;23(5):385-91. Ho WF, Koo SH, Yee JY, Lee JD
Genetic variations of the ABCC2 gene in the Chinese, Malay, and Indian populations of Singapore.
Drug Metab Pharmacokinet. 2008;23(5):385-91., [PMID:18974617]
Abstract [show]
MRP2 is a drug transporter that is responsible for the gastrointestinal absorption and biliary excretion of a wide variety of endogenous and xenobiotic compounds, including many clinically used drugs. This study aims to identify genetic variations of ABCC2 gene in three distinct ethnic groups of the Singaporean population (n = 288). The coding region of the gene encoding the transporter protein was screened for genetic variations in the study population by denaturing high-performance liquid chromatography and DNA sequencing. Twenty-two genetic variations of ABCC2, including 8 novel ones, were found: 1 in the 5' untranslated region, 10 in the coding exons (8 nonsynonymous and 2 synonymous variations), and 11 in the introns. Three novel nonsynonymous variations: 2686G > A (Glu896Lys), 4240C > T (His1414Tyr) and 4568A > C (Gln1523Pro) were detected in single heterozygous Malay, Chinese, and Indian subjects, respectively. Among the novel nonsynonymous variations, 4240C > T and 4568A > C were predicted to be functionally significant. These data would provide fundamental and useful information for pharmacogenetic studies on drugs that are substrates of MRP2 in Asians.

status: NEW49 This is also well in agreement with the fact that His1414Tyr and Gln1523Pro involve a larger degree of structural modification than Glu896Lys.

ABCC2 p.Glu896Lys 18974617:49:132
status: NEW52 Glu896Lys is the variant with the least drastic change, with both charged amino acid residues glutamate (acidic) and lysine (basic) having polar side chains, and thus likely to produce the mildest effect.
