Based on these findings, Celera sells a diagnostic gene test that purports to identify patients who can benefit from cholesterol lowering drugs.
Top cancer centers are already using the gene test to select patients.
Their six-gene test could split patients into high and low risk groups.
This is a very different situation from gene test for rare inherited diseases where most everyone who has the bad gene will get sick.
That's because very soon 40% of patients who previously might have gotten Erbitux will not get it any more because the gene test reveals in advance the drug won't work.
The new gene test could allow doctors to give the drug only to patients who are likely to benefit, and avoid those who are likely to just get side effects.
Now comes news that a gene test sold by Celera that claims to predict elevated risk of heart disease may be badly flawed and not signal heart risk at all.
This type of crowd-sourced gene analysis could be highly accurate, perhaps more so than a single company gene test where you have no way of knowing if the company has made a mistake.
FORBES: Do-It-Yourself Gene Testing Threatens Myriad's Monopoly
By combining the gene test for BRCA1 and BRCA2 with this extra genetic information, women who have a high number of the newly identified markers could find they have a nearly 100% risk of getting breast cancer.
But emerging new gene findings indicate that the high-priced drug may be useless in nearly half of colon cancer patients--and that a simple gene test could allow doctors to predict in advance which patients are likely to benefit.
On the other hand, some on Wall Street worry that availability of a gene test to predict response might limit the market for Iressa and Tarceva to only a small minority of lung cancer patients whose tumors have the gene mutations.
While its results may not provide the meticulous levels of accuracy the "speed gene" test delivers, it categorizes how likely a horse is -- genetically speaking -- to win.
The goal: a gene-based prognostic test, one that could predict years in advance which tumor will metastasize and kill you.
It will take several years to confirm the various gene findings and to test whether leukotriene-blockers work on human heart disease.
The company plans to move directly into a final-stage trial and is working on how to provide a diagnostic test for the gene.
But he said that the reasons for humans becoming addicted to any drug were more complex than simply their genetic make-up, and that a test for any gene uncovered by further research would not necessarily work.
Professor Patrick Morrison said they would test DNA for an altered gene that can cause the body to produce too much growth hormone.
When he finished in 1992, he didn't have enough funding left to put the gene in bacteria--a necessary test if he was to be sure he had the right DNA sequence.
Millennium's test detects melastatin, a skin gene that may slow cell division, and thus inhibit tumor growth.
For example, if you are a carrier of the cystic fibrosis gene (which is included in the Pathway test), and if your spouse is also a carrier, then as a couple you have a 25% chance of having a child with cystic fibrosis.
Test-tube experiments showed the Iceland gene causes the body's production of leukotrienes to go into overdrive.
It will come with a companion diagnostic test to spot patients who have the gene alteration.
