Cancer therapy has evolved from a "one-size-fits-all" type of treatment plan to a personalized approach based on a patient's type of cancer, the protein and genetic markers found in their tumors and their response to therapy. ...

Researchers studying a healthy population of young children have uncovered evidence for an association between a genetic marker that modulates the uptake of a particular brain chemical ('neurotransmitter'), serotonin (5-HTTLPR), ...

Resistance exercise has well-known health benefits, but the magnitude of those benefits may differ according to an individual's genetic make-up. Women with a high genetic risk of obesity may benefit less from resistance exercises ...

Patients with chronic myelomonocytic leukemia have limited treatment options, and those that exist are effective only in fewer than half of patients. Now, a new study identifies a panel of genetic markers that predicted which ...

Paclitaxel is a chemotherapeutic drug that has been shown to be highly effective when treating solid tumours, such as breast, ovarian and lung tumours. However, its use frequently causes peripheral neuropathies, neurological ...

In an international study, Mayo Clinic researchers and collaborators have identified genetic markers that may help in identifying individuals who could benefit from the alcoholism treatment drug acamprosate. The findings, ...

(Medical Xpress)—Scientists at Virginia Tech's Virginia Bioinformatics Institute working with the Center for Cancer and Blood Disorders at Children's National Medical Center have found a new way to diagnose brain cancer ...

Key genetic variants may affect how cancer patients respond to radiation treatments, according to a study published this week in Nature Genetics. The research team, which included researchers at the Icahn School of Medicine ...

Genetic marker

A genetic marker is a gene or DNA sequence with a known location on a chromosome and associated with a particular gene or trait. It can be described as a variation, which may arise due to mutation or alteration in the genomic loci, that can be observed. A genetic marker may be a short DNA sequence, such as a sequence surrounding a single base-pair change (single nucleotide polymorphism, SNP), or a long one, like minisatellites.
