Mutations in the insulin gene can cause permanent neonatal diabetes

Mutations in the insulin gene can cause permanent neonatal diabetes, an unusual form of diabetes that affects very young children and results in lifelong dependence on insulin injections, report researchers from the University of Chicago and Peninsula University (Exeter, UK) in Sept. 18, 2007, issue of the Proceedings of the National Academy of Sciences, published early online.

First common height gene identified by researchers behind 'obesity gene' finding

Whilst we all know that tall parents are more likely to have tall children, scientists have been unable to identify any common genes that make people taller than others. Now, however, scientists have identified the first gene, known as HMGA2, a common variant of which directly influences height.

Cause of major subtype of glaucoma discovered

In a paper published in the journal Science, scientists from deCODE genetics and academic colleagues from the National University Hospital in Reykjavik and Uppsala University in Sweden report the discovery of two common single letter variations (SNPs) in the sequence of the human genome that appear to account for virtually all cases of a major subtype of glaucoma.

Variant of the dopamine receptor gene may be associated with ADHD

A variant of the dopamine receptor gene may be associated with attention-deficit/hyperactivity disorder (ADHD) and with thinner tissue in areas of the brain that handle attention, but also appears associated with better clinical outcomes among individuals with the disorder, according to a report in the August issue of Archives of General Psychiatry , one of the JAMA/Archives journals.

Gene variant increases risk for alcoholism following childhood abuse

Girls who suffered childhood sexual abuse are more likely to develop alcoholism later in life if they possess a particular variant of a gene involved in the body's response to stress, according to a new study led by researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH).
