Pharmacogenetics News and Research

RSS

The terms pharmacogenomics and pharmacogenetics are often used interchangeably to describe a field of research focused on how genes affect individual responses to medicines. Whether a medicine works well for you—or whether it causes serious side effects—depends, to a certain extent, on your genes.

Just as genes contribute to whether you will be tall or short, black-haired or blond, your genes also determine how you will respond to medicines. Genes are like recipes—they carry instructions for making protein molecules. As medicines travel through your body, they interact with thousands of proteins. Small differences in the composition or quantities of these molecules can affect how medicines do their jobs.

These differences can be due to diet, level of activity, or the medicines a person takes, but they can also be due to differences in genes. By understanding the genetic basis of drug responses, scientists hope to enable doctors to prescribe the drugs and doses best suited for each individual.

Britain's Royal Society contributes little to medical science

The Royal Society today has contributed little to medical science and should undergo an urgent review of its purpose and programmes, states an editorial in this week’s issue of The Lancet.

Study shows genes predict how well diabetes drug will work

How well a person with type 2 diabetes responds to a diabetes drug may well depend upon his or her genetic make-up, according to a study published in the May issue of Diabetes Care. The study found that people who carried certain genotypes responded less favorably to rosiglitazone, a drug often prescribed for people with diabetes, than carriers of other genotypes.

Genes influence how heart failure patients respond to drugs

Genes dictate the color of our hair and eyes. They factor into whether we get cancer or heart disease. And, scientists increasingly recognize, they also ensure some patients will benefit from a prescription drug, while others develop adverse reactions or simply fail to respond at all.

Gene variations explain drug dose required to control seizures

Determining which variants of particular genes patients with epilepsy carry might enable doctors to better predict the dose of drugs necessary to control their seizures, suggest basic findings by researchers at the Duke University Institute for Genome Sciences & Policy (IGSP) and the University College London.

New guidelines mean tailor-made drugs are on the way

Many experts believe a milestone has been reached with the issuing of guidelines for pharmaceutical companies to encourage them to gather and submit information about how genetic variations affect the way people respond to their drugs.

Genetic markers implicated in fatal side effects of schizophrenia drug

Genaissance Pharmaceuticals today announced results from its CARING (Clozapine and Agranulocytosis Relationships Investigated by Genetics) study, reporting the discovery of genetic markers that the Company believes predict who is at risk of developing clozapine-induced agranulocytosis

Researchers step closer to cure for common childhood cancer

Acute lymphoblastic leukemia (ALL) is a malignant disease caused by the abnormal growth and development of white blood cells (WBC) in the bone marrow and blood. ALL is the most common cancer occurring in children with an annual rate of approximately 30 to 40 new cases per million.

Genetic evidence to support an inherited tendency to retain salt

Researchers at the University of Chicago have found genetic evidence to support the sodium-retention hypothesis, a controversial 30-year-old theory that the high rate of hypertension in certain ethnic groups is caused, in part, by an inherited tendency to retain salt.

Genes affect how asthma patients respond to albuterol

While a few weeks of regular use of albuterol improved overall asthma control in individuals with one form of the gene, stopping all use of albuterol eventually improved asthma control in those with another form of the gene. Albuterol is the most commonly used drug for relief of acute asthma symptoms, or “attacks.”

Investigation into the potential for designing drug treatments based on a person’s genetic makeup

Most current drugs are not effective for 100 per cent of the population and some work in as few as 30 to 50 per cent of cases. Pharmacogenetics, the study of how genetic factors influence a person’s response to a drug, is seen as a way of making treatments as safe and effective as possible for every individual.
