Genetic tests for all - the new approach to preventive medicine
Mark Henderson and Sam Lister
Genetic tests that can detect a raised risk of breast, ovarian and prostate cancer are being offered for the first time to people without family histories of the diseases, The Times has learnt.
The programme, run by University College London (UCL), paves the way for a new approach to preventive medicine involving widespread screening. It will also prompt greater demand for screening of embryos by parents who carry a defective gene and want to avoid passing it to their children.
News of the programme came as Paul Serhal, medical director at University College Hospital’s Assisted Conception Unit, announced the birth of one of the world’s first babies selected to be free of a genetic risk of breast cancer. The girl was born after embryos were screened to exclude the faulty BRCA1 gene. All the father’s female relatives had developed breast cancer caused by BRCA1. The gene gives a woman an 80 per cent chance of developing breast cancer in her lifetime and raises the risk of ovarian and prostate cancer.
The two developments show the speed with which advances in genetic screening are having an impact on patient care. Genetic tests can now identify people with heightened risks of chronic conditions such as heart disease and diabetes and even high cholesterol.
Embryo screening, which is licensed for certain serious conditions, such as Huntington’s disease and cystic fibrosis, continues to attract controversy, with claims that it is paving the way for the creation of “designer babies”. However, doctors’ leaders argue that a technique that can prevent a child from developing a life-threatening illness should not be restricted.
The UCL screening programme is focusing on the London community of Ashkenazi Jews, who have a high risk of inheriting BRCA1 and BRCA2. The NHS offers BRCA testing, but only for women whose relatives have had cancer because of the mutations. Up to 50 per cent of people with the faulty genes do not have a family history of the diseases, largely because the gene can be carried by men.
"'I'll make old vases for you if you want them—will make them just as I made these.' He had visions of a room full of golden brown beard. It was the most appalling thing he had ever witnessed, and there was no trickery about it. The beard had actually grown before his eyes, and it had now reached to the second button of the Clockwork man's waistcoat. And, at any moment, Mrs. Masters might return! "Worth stealing," a Society journalist lounging by remarked. "I could write a novel, only I can never think of a plot. Your old housekeeper is asleep long ago. Where do you carry your latchkey?" "Never lose your temper," he said. "It leads to apoplexy. Ah, my fine madam, you thought to pinch me, but I have pinched you instead." How does that strike you, Mr. Smith? Fancy Jerusha Abbott, (individually) ever pat me on the head, Daddy? I don't believe so-- The confusion was partly inherited from Aristotle. When discussing the psychology of that philosopher, we showed that his active Nous is no other than the idea of which we are at any moment actually conscious. Our own reason is the passive Nous, whose identity is lost in the multiplicity of objects with which it becomes identified in turn. But Aristotle was careful not to let the personality of God, or the supreme Nous, be endangered by resolving it into the totality of substantial forms which constitute Nature. God is self-conscious in the strictest sense. He thinks nothing but himself. Again, the subjective starting-point of305 Plotinus may have affected his conception of the universal Nous. A single individual may isolate himself from his fellows in so far as he is a sentient being; he cannot do so in so far as he is a rational being. His reason always addresses itself to the reason of some one else—a fact nowhere brought out so clearly as in the dialectic philosophy of Socrates and Plato. Then, when an agreement has been established, their minds, before so sharply divided, seem to be, after all, only different personifications of the same universal spirit. Hence reason, no less than its objects, comes to be conceived as both many and one. And this synthesis of contradictories meets us in modern German as well as in ancient Greek philosophy. 216 "I shall be mighty glad when we git this outfit to Chattanoogy," sighed Si.
