All of the heart patients in the study had one of two bad gene variants discovered last year by DeCode that are believed to increase levels of inflammation in the arteries (see: " Attacking Heart Attacks").
In a study of people with a gene that put them at higher risk for Alzheimer's, those who ate a high-fat diet were seven times more likely to develop the disease than those who ate a low-fat diet, researchers reported.

In most cases in this study, a bad copy of a gene from a parent was not to blame.

Doctors from Queen Mary, University of London, are also taking part in the study that looks for a gene called AIP, which causes abnormal growth of the pituitary gland.
The Nottingham study examined gene activity in 74 samples of ependymoma.
Instead of looking at a single gene or protein in isolation, researchers may one day study all of them at once to understand how the body functions and how things go wrong, charting for the first time the intricate biochemical chain reactions that lead to heart disease, diabetes or schizophrenia--and gaining astonishing insights into cures.
The gene at the heart of the study is the one that caused 18th century patient Charles Byrne, born near Cookstown in County Tyrone and known as the 'Irish giant', to grow to more than seven and a half feet tall.
In a study of over 1000 Iceland residents with osteoporosis, the firm found that those with certain bad versions of a gene called BMP-2 were three times more likely to develop osteoporosis.
Study of these fragments showed that they sometimes differed from one another in three places along the length of the gene although this did not prove that any or all of those variations caused a difference in coat colour.
The study found that volunteers with two copies of the "val" gene were better able to break down dopamine and suffered less pain.
While patients with the KIF6 gene who were in the placebo arms of the drug studies had elevated heart risk, the risk seemed to decline dramatically or dissappear among patients with the gene variant who were in the arms of the study that got the cholesterol-lowering drugs.
In 1995 DuPont and Genencor began using sophisticated gene chips that let them study RNA activity inside the nucleus of E. coli bacteria.
As well as identifying the lupus genes, the study will also attempt to recognise gene patterns that could cause more serious forms of the disease in order to monitor who could have acute problems in the future.
In a study of more than 1, 500 heart patients in two countries, the Icelandic gene-hunting firm found that defects in a crucial inflammation-causing gene nearly doubled the risk of heart attack and boosted the risk of stroke by 67%.
The Imperial study, of more than 1, 200 people, identified two forms of the GAD2 gene.
The gene therapy team at Great Ormond Street Hospital was highly critical of the study.
One disease under study is cystic fibrosis, which is caused by one of around 200 defects on a single gene.
In 2010 a study published by Dr Fowler and his colleagues implicated a gene known as DRD4 in the development of political affiliation.
Paul Ridker, the Harvard cardiologist who headed up the study, notes that all of these patients should still be taking cholesterol drugs, and that this gene alone probably won't be turned into a diagnostic test.
One study from the General Accounting Office looked at gene scan services marketed to consumers and found a host of misleading results.
There is a good chance that Nabil is of Phoenician descent - the study has revealed that while one in 17 people across the Mediterranean carry the Phoenician gene, in Lebanon almost a third of the population have Phoenician roots.
