It is also highly expressed in areas of the central nervous system, including the substantia nigra. The fast or slow rate of caffeine breakdown has no direct effect on the heart rate since these side-effects are attributed to the chemical properties of caffeine. The CYP family of enzymes breaks down both toxins and medications. People with the AA genotype at rs762551 (within the CYP1A2 gene) are “fast metabolizers” while those with the AC or CC are “slow metabolizers.” (6 and 7). Like caffeine, you may be a "fast" or "slow" metabolizer of your catecholamine hormones. The CYP2C9 enzyme breaks down (metabolizes) compounds including steroid hormones and fatty acids. Free weekly newsletter with latest articles and interesting health research. CYP1A2 gene: This gene codes for the enzyme that metabolizes, or breaks down, caffeine in the body. AA = CYP1A2*1F = Fast Metabolizer. Intermediate Metabolizer: An intermediate-metabolizing enzyme is considered to be less active. This gene codes for the enzyme that metabolizes, or breaks down, caffeine in the body. Ultrarapid Metabolizer (UM) – This means there are two copies of a CYP2C19 gene with increased activity. Click here to learn more and subscribe today! Multiple variations (polymorphisms) in the CYP2C19 gene have been associated with clopidogrel resistance, a condition in which the drug clopidogrel is less effective than normal in people who are treated with it. You may be a rapid metabolizer for one drug, and a normal metabolizer for a different drug. News and Research: Melatonin study for middle-aged primary insomnia, A fast metabolizer taking omeprazole (Prilosec) to treat, Alternatively, some drugs such as Plavix convert into their active drug state through CYP2C19.
