|
Definition
CYP2D6 (enzyme that possesses genetic variants affecting drug metabolism) |
|
|
Term
Allele 1 = normal phenotype Alleles2 and 3 = poor metabolizers |
|
Definition
Cyp2C19 (enzyme that possesses genetic variants affecting drug metabolism) |
|
|
Term
No gene expression or dysfunctional protein |
|
Definition
DNA fragment deletions or insertions into genes (altered gene DNA sequence) |
|
|
Term
If inserted intact, increased gene expression and protein levels; If not inserted intact --> DNA fragment insertion |
|
Definition
Gene duplication or increased copy number of genes (altered gene DNA sequence) |
|
|
Term
most common cause of gene sequence variation; SNP --> phenotypic change and can increase risk of disease; most SNP's occur in introns and rarely cause phenotypic disease |
|
Definition
Single Nucelotide Polymorphism (Altered Gene DNA sequence) |

Definition
alteration of drug pharmacodynamics i.e. how patient responds |
|
|
Term

Definition
Abnormal Drug Pharmacokinetics |
|
|
Term
Mechanisms of management strategies that are used to alter the pathophysiological symptoms |
