It revealed little about how minute genetic variations among people can lead to common diseases.
And very recent studies have suggested how certain genetic variations might be involved in internet addiction.
Last month, scientists from 11 Asian countries formed a consortium to study genetic variations in their populations.

"We need to explore the genetic variations related to insulin secretion, " says Carnethon.

The scientists looked for common genetic variations - known as single nucleotide polymorphisms (Snps) - linked to the three cancers.
Scangos says companies should start looking for genetic variations that predict a drug's efficacy in the very early stages of clinical testing.
Genetic variations between people are associated with different levels of working memory.
Some researchers call for a massive new effort to analyze thousands of various tumors to glean a better understanding of their genetic variations.
"Everyone has genetic variations" many of which will never cause disease, says Michael S. Watson, executive director of the American College of Medical Genetics and Genomics, a professional organization.
These are tiny glass chips dotted with thousands of microscopic wells where DNA fragments react with other chemicals in order to measure the activity of genes or identify genetic variations.
Scientists have looked at anger and violence, though, and discovered genetic variations, expressed as concentrations of a particular messenger molecule in the brain, that are both congenital and predisposing to a violent temper.

Unfortunately, because the individual risks associated are generally very small, and the genetic variations are very common, for most diseases this means we are unlikely to be able to predict the likelihood of developing disease in individual patients.
The two companies aim to help gene researchers quickly sift through the massive amounts of DNA data and medical record information in search of crucial genetic variations that can increase the risk of everything from heart disease to diabetes.
Only by understanding the subtle genetic variations among hundreds of thousands of people--by sifting out the molecular misnomers that predispose someone to a particular malady--will scientists learn how to better predict, diagnose and ultimately cure difficult diseases like diabetes, schizophrenia and heart failure.

By comparing genomes across thousands of people, researchers identified genetic variations at 24 different points in the human genome that are linked with eye and hair colors, which past studies used to help determine the appearance of people who had died relatively recently.
Dr Ron Fouchier, from the Erasmus Medical Center in Rotterdam, said his team had introduced a number of genetic variations - around five - which had enabled the virus to pass between ferrets - the best animal model we have for testing whether the virus will infect humans.
The different cells of a tumor actually have subtle variations in their genetic form because of mutations as the cells reproduce.
In an accompanying commentary, Prof Ian Small from the University of Western Australia - who was not involved in the research - said the vast variations between the genetic data of angiosperms gleaned from mitochondrial genome sequencing made " untangling their evolutionary histories difficult".
It is now known that genetic variability accounts for 25% of susceptibility to the disease, but that variations in the sickle-cell gene contribute to only a fraction of that.

It plans to cull these variations to find particular mutations that predispose patients to major killers and also to genetic alterations that increase the risk of side effects from prescription drugs.
But thanks to new genetic data, the researchers at Terlings Park have gradually begun to identify and locate subtle variations among receptors, enabling them to develop drugs to target them far more precisely.
Genetic disorders, such as cystic fibrosis, muscular dystrophy and haemophilia, are caused by mutant variations of normal genes which are unable to perform their proper function.
