DNA used to pinpoint ancestors' villages
An individual's genome can be used to accurately predict their ancestral origin, to the nearest five miles, a new study has found...
In genetic epidemiology, an association is the observed connection between a trait and a particular version of a gene or other genetic variant.
Genome-wide association studies (GWAS) are used to pinpoint variants associated with complex disorders or traits, which are caused by the interaction of multiple genetic and non-genetic factors.

Stepping into the contentious world of race, ethnicity and genetics, a paper published in this week's Nature claims to have shed new light on the geographical origin of the many 'Jewish Diaspora' communities from around the world...
Last week, BioNews reported on a study published in Science that claimed to have identified several gene clusters associated with longevity. The study drew significant media interest but, following the paper's publication, experts have raised concerns about the data...
Scientists have identified 12 new gene variants associated with type 2 diabetes, according to recent work published in Nature Genetics...
A study investigating the effects of common large DNA deletions and duplications has found no new links to complex disease...
Breast cancer risk prediction does not improve significantly when genetic information is included in the risk prediction model, a new study published in the New England Journal of Medicine has found....

In their concluding remarks, all three speakers said the answer to the question implicit in the event's title - if you are genetically predisposed to a neurodevelopmental disorder, does this effectively mean you are marked for life? - is an emphatic 'no'. Nonetheless, they had divergent views on the likelihood of successfully applying the fruits of genetic research into mental health...
A genetic risk score based on several genetic markers associated with cardiovascular disease (CVD) does not improve the prediction of CVD risk, research published in the Journal of the American Medical Association has suggested...
The Counsyl 'Universal Genetic Test' has a distinctly 'retro' feel to it. With its focus on Mendelian disorders (i.e. classic genetic diseases like cystic fibrosis), many of the ethical issues raised by this new service are not new themselves, but rather present new challenges...

An international team of 174 research centres has identified 13 new gene variants associated with blood glucose and insulin, with five linked to Type-2 diabetes. The findings - published last week in the journal Nature Genetics -raise hopes of better treatments for the condition....
