Smokers Genes Could Predict Who Benefits Most From Cessation Medications

Smokers Genes Could Predict Who Benefits Most From Cessation Medications

The same gene variations that make it difficult to stop smoking also increase the likelihood that heavy smokers will respond to nicotine-replacement therapy and drugs that thwart cravings, a new study shows.

Strong Risk Factor For Bipolar Disorder Associated With NCAN Genetic Variation

Strong Risk Factor For Bipolar Disorder Associated With NCAN Genetic Variation

A genetic variation in the gene neurocan (NCAN) could denote a strong risk factor for bipolar disorder, new research suggests. The study into the genetic basis of bipolar disorder, published in the American Journal of Human Genetics, considered the DNA of a large number of people with bipolar disorder in Europe, Australia and the USA. Through their GWAS investigation, they discovered that the genetic variation of NCAN was significantly associated with thousands of patients who suffer from bipolar disorder.
