Maybe you spent hundreds of dollars on gifts. DNA is like a set of instructions for your body that can help decide how well your enzymes will work. DNA is like a set of instructions for your body that can help decide how well your enzymes will work. A pharmacogenomic test, administered by your physician, can give you insights about how your body processes certain medications based on your genetic metabolism rate. Consider this case:  Two patients each take the same dose of the same antidepressant medication. Follow your health care provider's instructions when taking any medication. Mayo Clinic does not endorse any of the third party products and services advertised. This section provides information only about this specific pharmacogenomic test. The part of DNA that instructs how well the CYP2C19 enzyme will work is called the CYP2C19 gene. 2.0 -2.5) indicates the patient MAY be an ultra-rapid metabolizer, the phenotype assigned will be: CYP2D6 possible ultra -rapid metabolizer • If an activity score (e.g. Cytochrome P450 is a family of enzymes involved in the rate and extent of drug metabolism. If you are a healthcare provider and interested in learning more about the GeneSight test, please call us at 855.891.9415. The study of how genes like CYP2D6 affect the way you break down medicines is called pharmacogenetics (FAR mah coh je NEH tiks). “I think most (doctors) understand how faulty the point of care tests can be, especially pain physicians. On the other hand, ultra-rapid metabolizers are more prone to the adverse effects of codeine and tramadol (review of 46 studies) . She also received a card that noted Madilyn was a normal metabolizer of the CYP2D6 and CYP2C9 enzymes, as well as an ultra-rapid metabolizer of CYP2C19. Differences in your DNA that make u… Talk with your healthcare provider about choosing a medication may be a better option for you. How can this be? Ultra-rapid metabolizers (UM) carry multiple copies of functional alleles leading to excess activity. If you are a patient, please talk with your doctor to see if the GeneSight test may be helpful. Most often, changes in the CYP2C19 gene lead to impaired metabolism of these drugs, which reduces their effectiveness. Routine testing for codeine and CYP2D6 is not recommended. The CYP2C19 gene test results have placed your child into the Ultrarapid Metabolizer (UM) group. The FDA drug label for codeine states that even at labeled dosage regimens, individuals who are ultra-rapid metabolizers may have life-threatening or fatal respiratory depression or experience signs of overdose. The study of how genes like CYP2C19 affect the way you break down medicines is called pharmacogenetics (FAR mah coh je NEH tiks).

I am a ultra rapid metabolizer and my dr and I have been trying to get my dosage right on my adderall. Check your genetic data below. Patient's enzymes process medications a little faster than a poor metabolizer, but slower than a normal metabolizer. Each person differs from another at the DNA (gene) level. There are two possibilities with this test result. Ultra-rapid metabolizer – medication is rapidly broken down. The GeneSight test must be ordered by and used only in consultation with a healthcare provider who can prescribe medications. These genes and enzymes help determine our individual rate of metabolism, which varies from person to person. Poor Metabolizer: A poor-metabolizing enzyme has very low activity. The CYP2C19 gene test results have placed your child into the Rapid Metabolizer (RM) group. The clinical history of these persons is quite typical and I share this information to help practitioners identify pain patients who may have a genetic defect of CYP-2D6. Included in this cohort is a single patient who has CYP-2D6 gene duplicity and is termed a rapid- or ultra-metabolizer. Codeine is a medication used for pain relief. If you have medication questions, ask your health care provider. Medication may be removed from your system too quickly to provide any symptom relief. The importance of CYP1A2 for druginteractions has been increasing overthe past decade due to the growingnumber of drugs metabolized by thisenzyme.1Drugs metabolized by CYP1A2are called CYP1A2 substrates.

Additionally, if a patient is an ultra-rapid metabolizer of certain opioid medications, they may appear to be abusing or drug-seeking when, in fact, they are simply not receiving their optimal dose of medication. Each person differs from another at the DNA (gene) level. Interpretation: The effect of the genotype on enzyme activity could not be fully determined. Variants in the CYP2D6 gene influence the way your body processes (metabolizes) codeine and can affect your response to this medication.

The answer lies in our genes. Individuals with two copies of the CYP2C19*17 polymorphism are typically classified as ultra-rapid metabolizers.

Sometimes it is used as a cough suppressant. 0 -0.5) indicates the patient MAY be a poor metabolizer, the phenotype assigned will be: CYP2D6 possible poor metabolizer a) Ultra-rapid metabolizer (UM) b) Intermediate metabolizer (IM) c) Poor metabolizer (PM) d) Indeterminate . Poor metabolizer • If an activity score (e.g. Extensive metabolizers (EM) have two normal or “wild-type” alleles and are considered to have normal metabolism. As with all genetic tests, the GeneSight test results have limitations and do not constitute medical advice. A single copy of these materials may be reprinted for noncommercial personal use only. Someone from your team (your doctor, your nurse practitioner or a clinical pharmacist) will review with you the results of your child’s test and explain how we will personalize your child’s medications based upon these test results.

Routine testing for codeine and CYP2D6 is usually not done. Patients who have a CYP2D6 variant that metabolizes codeine quickly may experience side effects such as nausea, vomiting, constipation, difficulty urinating, drowsiness, decreased mental alertness and a reduced urge to breathe.
