74004-3
LaboratoryABCB1 gene mutations found [Identifier] in Blood or Tissue by Molecular genetics method Nominal
Definition
ABCB1 (MDR1) gene mutation analysis is performed on patients who present with ineffectiveness or toxicity to certain drugs (protein MDR1 substrates). The patient's genotype is used to predict expression and activity of MDR1 enzymes (that regulate the transport of many drugs) and to determine appropriate treatment and drug dosage.
