Three genes that have barely been studied to date have now provided fresh knowledge about patients with suicidal backgrounds. This is the result of a study by a team of Spanish researchers at Mount Sinai Hospital and Columbia University in the City of New York (United States), which found that several mutations are involved. This finding could help to develop future genetic tests to identify predisposition to suicide, without ignoring the importance of social and cultural factors. "There is...

A tool for clinicians as well as geneaologists Understanding the genetic ancestry of mixed populations, such as those found in North America, can not only help to detect their origins but also to understand the genetic basis of complex diseases, a scientist will tell the annual conference of the European Society of Human Genetics today (Saturday June 11). It is the first time that the genomes of individuals of admixed ancestry have been sequenced in such detail, says Dr. Francisco De La Vega...

New studies have found that Jews share a genetic bond with Cypriots and Druze and verifies the Jewish Diaspora maintained a strong DNA continuity despite its long separation from the Middle East, according to scientists on Wednesday. The work is part of a larger exploration into human migration based on groups of tiny differences in genetic codes. "We found evidence that Jewish communities originated in the Near East," said molecular scientist Doron Behar of the Rambam Health Care Campus in...

ASHG publishes follow-up white paper report that explains scientific reasoning and expands on recommendations made in 2008 policy statement Genetic ancestry testing is a practice that has become increasingly popular in the U.S. over the past few years. An estimated half-million Americans will purchase genetic ancestry tests from one of the approximately 40 companies worldwide that currently provide this type of service to consumers. However, increasing public interest in Direct-to-Consumer...

-- New Approach Also Specifies Results for Individual Patients -- PHILADELPHIA, April 29 /PRNewswire-USNewswire/ -- In findings that may speed the search for disease-causing genes, a new study challenges the prevailing view that common diseases are usually caused by common gene variants (mutations). Instead, say genetics researchers, the culprits may be numerous rare variants, located in DNA sequences farther away from the original "hot spots" than scientists have been accustomed to look....

Agronomists at Iowa State University are offering doubled haploid technology that allows corn breeders to more quickly produce inbred lines for research or private use. Thomas Lbberstedt, associate professor and K.J. Frey chair in agronomy and director of the R.F. Baker Center for Plant Breeding, has launched a Doubled Haploid Facility at ISU that can develop pure, inbred corn lines in less time than traditional methods. Inbred corn lines have two copies of the same genome. They are sometimes...

Grapes are one of the world's most economically important fruit crops, but the woody perennial takes three years to go from seed to fruit, and that makes traditional breeding expensive and time-consuming. A team of Agricultural Research Service (ARS) researchers has found a way to speed things up by developing a way to identify genetic markers in the grapevine's genome that can be linked with specific traits, such as fruit quality, environmental adaptation, and disease and pest resistance....

In the ongoing quest to identify the genetic factors involved in disease, scientists have increasingly turned to genome-wide association studies, or GWAS, which enable the scanning of up to a million genetic markers in thousands of individuals. These studies generally compare the frequency of genetic variants between two groups "” those with a particular disease and healthy individuals. Differences in the frequency of a given variant suggest the variant may be involved in the disease....

Alcohol dependence (AD) is a complex disease for which both genetic and environmental factors affect susceptibility. Previous research had identified several genes associated with AD through linkage analysis or candidate-gene approaches. Findings from a genome-wide association study (GWAS) support an association between AD and a cluster of genes on chromosome 11. Results will be published in the May 2010 issue of Alcoholism: Clinical & Experimental Research and are currently available at...

A few minor variations in one gene may make a difference in athletic endurance, according to a new study from Physiological Genomics. The study found that elite endurance athletes were more likely to have variations of the NRF2 gene than elite sprinters. Non-elite endurance athletes were also more likely to have the genetic variations compared to sprinters, although the difference was not as pronounced. The study shows an association between the gene variation and endurance, but does not...

House Mouse, Mus musculus
2012-05-01 11:42:07

Even in the wild, this rodent is associated with humans by destroying crops and stored food. The house mouse is also known as the fancy mouse, a common pet. It is also a widely used laboratory animal, important for testing in genetics, biology, and medicine. There are three recognized subspecies of the house mouse. These mice thrive in a number of locations including fields, houses, and commercial structures. An adult male house mouse can have a body length of up to 3.9 in, and tail length...
