This section provides a summary of the gene/protein's function, expression, and relevance to neurodegenerative diseases.
CYP2D6 encodes cytochrome P450 2D6, a member of the cytochrome P450 superfamily of enzymes. CYP2D6 metabolizes approximately 25% of all drugs, including many used in neurology and psychiatry. It catalyzes the oxidation of a wide range of substrates, including antidepressants, antipsychotics, beta-blockers, and opioids. CYP2D6 is also involved in the metabolism of neuroactive compounds and has been implicated in the bioactivation of pro-neurotoxic compounds. The enzyme is highly polymorphic, with over 100 known alleles affecting enzyme activity.
Highest expression in liver. In the brain, expressed in various regions including cortex, hippocampus, and substantia nigra. Brain CYP2D6 may have local drug metabolism and neurotoxin processing functions. Expression is inducible by certain drugs and environmental factors.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Parkinson's Disease | Various | Risk factor | Metabolism of neurotoxins |
| Alzheimer's Disease | Various | Risk factor | Drug metabolism alterations |
| Drug Metabolism Disorders | Various | Various | Poor/ultra-rapid metabolizer status |
