Vitamin K: CYP4F2 and VKORC1 Genetic Variants
Genetic variations cause people to have higher or lower levels of vitamin K, which can affect blood clotting. Learn more about the genes that affect vitamin K and how it relates to your genetic raw data.
Detoxification & Metabolism of Medications
Genetic variants about in the enzymes that break down drugs and toxins. These genetic differences are why some medications don’t work well for certain people. Our reactions to toxicants, such as pesticides, also relies on our genes.
CYP2C19 – Metabolizing medications
Several popular drugs such as Prilosec, Nexium, and Plavix are metabolized by the CYP2C19 enzyme. There are important genetic variants in the CYP2C19 gene that changes how fast or slowly these drugs are broken down. Learn how these variants might affect their efficacy. (Member’s article)
GSTs: glutathione-S-transferase enzymes for detoxifying environmental toxins.
We are exposed to many different man-made chemical compounds every day, with exposure to new toxicants being much higher than what our ancestors experienced. There are several common GST variants that decrease the function of the GST enzymes. (Member’s article)
CYP1A2 – Breaking down caffeine and more
The CYP1A2 gene breaks down caffeine, several major prescription drugs, and interacts with smoking. Learn how your genes influence caffeine metabolism and more. (Member’s article)
SOD1: Genetic Variants in Our Antioxidant Defense System
Our body has built-in antioxidants that fight against cellular stress. The superoxide dismutase enzyme fights against oxidative stress in your cells.
Detoxifying Phthalates: Genes and Diet
Phthalates are a type of chemical used as plasticizers to make plastics more pliable. There has been a lot of research on the endocrine-disrupting effects of phthalates. Your genetic variants may impact whether phthalates are a problem for you.
Nrf2 Pathway: Increasing the body’s ability to get rid of toxins
The Nrf2 (Nuclear factor erythroid 2–related factor) signaling pathway regulates the expression of antioxidants and phase II detoxification enzymes. This is a fundamental pathway that is important in how well your body functions. Your genetic variants in the NFE2L2 gene impact this NRF2 pathway.
CYP2A6: Breaking down nicotine and other medications
How many cigarettes a day a person smokes – and how hard it is for them to quit – is at least partly dependent on the CYP2A6 gene. This enzyme also metabolizes several important cancer drugs.
CYP1A1: Detoxifying Cigarette Smoke and Estrogen
This phase I detoxification gene is important in the breakdown of the hydrocarbons produced in smoke and air pollution. It also affects the metabolism of estrogen.
Tamiflu
Genetic variants impact how well the flu antiviral medication, Tamiflu, works for an individual. Learn how your genes impact this medication. (Member’s article)
Why Allegra May Not Work For You
Ever wonder why a certain medication may work great for a friend and do nothing for you? One reason could be the genes involved in transporting the medication into and out of your cells.
This article looks at the research studies on fexofenadine (Allegra) and the Multidrug Resistance Protein variants. (Member’s article)
Drinking Genes: How well do you break down alcohol?
Wondering why you don’t react the same way to alcohol as your friends do? Some people metabolize alcohol faster leaving a build-up of acetaldehyde. Learn more about why this can be a health problem for some. (Member’s article)
Glucuronidation: UGT genetic variants, phase II detoxification
The UGT family of enzymes are responsible for an important part of phase II detoxification. This article explains what the UGT enzymes do in the body, how your genes impact this part of detoxification, and lifestyle factors that can increase or decrease this detox process.
CYP2C8: Prescription medications and arachidonic acid
The CYP2C8 gene is important in the metabolism of several chemotherapy drugs (e.g. Taxol) as well as playing a role in the metabolism of NSAIDs. Genetic variants that alter the way that this enzyme works can impact your reaction to a medication.
Will statins give you muscle pain? What your genes can tell you.
Statins are one of the most prescribed medications in the world. One side effect of statins is myopathy, or muscle pain and weakness. Your genetic variants are important in whether you are likely to have side effects from statins.
NQO1 Gene: Metabolism of quinones, benzene, and more
The NQO1 gene codes for an important enzyme in phase II detoxification. This enzyme is responsible for metabolizing the cancer-causing benzene (e.g. from air pollution) and cigarette toxins. Learn more and check your genes. (Member’s article)
