A new study of twins suggests that attention - deficit hyperactivity disorder (ADHD) is strongly linked to genes, and that it is less a clear - cut disorder than an extreme form of a trait, like blood pressure, that varies throughout the population.

In the first study to show that the sensations from sampled alcohol vary as a function of genetics, researchers focused on three chemosensory genes — two bitter - taste receptor genes known as TAS2R13 and TAS2R38 and a burn receptor gene, TRPV1.

One study even identified two genes in which particular variants can slow the onset of AIDS, demonstrating the potential of this approach for understanding why people vary in their susceptibility to infectious diseases.

In their recent paper, the researchers not only looked at the genetic code, but also studied how gene activity varied between the two populations.

Published in Nature Communications, the study analysed a population of over 6,000 people with varied ancestry across Latin America to identify new genes associated with hair color, greying, density and shape, i.e. straight or curly.

Geneticists usually prefer to study genes that are easy to mutate so that work can be replicated or varied, but only one lin - 4 mutation had ever been observed, in Brenner's Cambridge lab a few years earlier.

In the Oncogene study, the research team found key distinctions in how these mutated genes give rise to PLGGs, a varied group of cancers that collectively account for the most common brain tumor in children.

Increasingly local adaptation to climate is being studied at the molecular level by identifying which genes control climate adaptation and how these vary between individuals.

These mutations varied tremendously between populations, which counters a popular view that many of the differences between populations arose by chance or were genetic variants that hitchhiked along with other genes that improved reproductive success, says biological anthropologist Henry Harpending of the University of Utah, Salt Lake City, and co-author of another study of accelerated evolution.

A new study published in the current issue of Biological Psychiatry, by researchers at Cardiff University School of Medicine and the University of Bristol, suggests that there is a spectrum of attention, hyperactivity / impulsiveness and language function in society, with varying degrees of these impairments associated with clusters of genes linked with the risk for ADHD.

Although the gene sequences from human and chimpanzee remain very similar, previous studies in tissues other than the brain have shown that gene expression varies widely.

In this study, we examined whether the potential to utilise global regulatory mechanisms to control gene expression through chromatin organisation varies between housekeeping and tissue specific genes (Hkg and Tsg respectively) by virtue of their organisation.

Studies on mutations of animals as varied as yeast, slime molds, plants and mice show that deletions of autophagy related genes (ATG) in animals is largely incompatible with life.

The purpose of this study is to 1) investigate the morphology of the pigment producing cells (melanocytes) and determine if any ultrastructural differences exist among varying appaloosa genotypes, and 2) examine previously associated genes to determine the biological mechanism of pigment loss.
