(ABCC2 Val417Ile)

Short summary

Associated with increased activity of the intestinal efflux transporter ABCC2, evidenced by gene-dose related decrease of oral absorption and increased residual clearance of talinolol.

Participants with at least one variant allele of V417I (n=13) had about 20% lower AUC and bioavailability (AUC: 2730±654 ng×h/ml vs. 3420±708 ng×h/ml, P<0.05; F: 60.3%±14.0% vs. 75.1%±12.0%, P<0.05).

  • [carbamazepine]
    Risk or phenotype-associated allele: A. Phenotype: This SNP showed a strong association with the neurological adverse drug reaction caused (ADR) by carbamazepine (P=0.005). The study results indicate that the c.1249A variant is an independent risk factor of carbamazepine CNS ADR. Study size: 146 patients with epilepsy who had been prescribed carbamazepine. Study population: Korean.
  • Common variant, mostly found to have no association, but there was one exception.
  • [talinolol]
    The A allele of this variant is associated in a gene dose dependent manner with the following phenotypes: 1) increased residual clearance of intravenous talinolol and 2) lower bioavailablilty of orally administered talinolol in healthy German subjects. However, this variant is not associated with alterations in intestinal ABCC2 mRNA or protein levels.
