Warnings over shock dementia revelations from ancestry DNA tests

Provide counselling and companies have been Advised to Take moral responsibility

People who use genetic tests to trace their ancestry only to discover that they are in danger of succumbing to an incurable illness are being abandoned to suffer severe problems. Dementia researchers say the challenge is particularly severe for individuals found to be at risk of Alzheimer’s disease, which has no cure or effective treatment. After attempting to find their Asian Asian or early Greek origins yet these individuals are stumbling upon their standing.

“These evaluations have the capacity to cause great distress,” explained Anna Middleton, head of society and ethics research in the Wellcome Genome Campus in Cambridge. “Businesses should make counselling available, before and after individuals take tests.” The issue is raised in a newspaper by Middleton and others in the journal Future Medication.

There was A similar warning sounded by Louise Walker, research officer in the Alzheimer’s Society. “Everybody has a right to learn in their risk if they would like to, but these companies have a moral responsibility to be sure men and women understand the meaning and consequences of this information. Anyone contemplating getting genetic evaluation results should do so with their eyes open.”

Alzheimer’s is linked to the build-up in the mind of clumps of a protein called amyloid. This triggers serious memory loss, confusion and disorientation. This procedure, impacts and is present in three versions: E3 E2 and E4. Those face an increased chance of getting the disease in late life.

“Approximately 3% of the population has two copies of the E4 version — one inherited from each parent,” Professor John Hardy, of University College London, said. “They have about an 80% chance of getting Alzheimer’s from age 80. The typical man has a 10% risk.”

The connection with ApoE was made in 1996 and the reaction was remembered by Hardy . “We went around testing ourselves to determine which version we possessed. I discovered I have two low-risk E3 variations on my genome. But if I had discovered two E4 versions? By today I would be facing the possibility I had a serious chance of getting Alzheimer’s disease in ten decades. I would be pretty fed up.”

The ability to discover a person status has become even easier as a result of the evolution of genetic tests that provide information about a person’s ancestry, health risks and attributes that are general. Dozens of companies offer such advertisements and services portray happy people learning in their origins — 43% African American or 51% Middle Eastern — often to the sound of Julie Andrews singing Getting to Know You or a similarly happy-sounding track. All you’ve got to do is supply a sample of spittle.

The subsequent information about predilections to disease isn’t stressed — but it’s given. Since she wished to prove her mother’s family came from Spain, Kelly Boughtflower, from London, chose a receptor test with the business 23andMe. The results provided no evidence of her Iberian roots but shown she transported one edition although not as radically as a double dose.

“I did not consider it at the moment,” explained Boughtflower. “Then, once I took up work as a Alzheimer’s Society support employee, I heard about ApoE4 and the information has come to sit very profoundly with me. Did I inherit the ApoE4 from my mom? Is she likely to get Alzheimer? Do I passed it on to my own daughter? I have attempted to get counselling on the NHS but that isn’t readily available for a person in my specific predicament, I had been told.”

Other examples appear on the ApoE4 Information site, a forum for those whose gene evaluations show an Alzheimer’s susceptibility. “Have stumbled upon my 4/4 ApoE status. I am still in shock,” writes one. Another states: “I have paid a $50 Amazon gift-card to share in a genetic study. I had been naive and unprepared.”

There is not any medication or treatment for Alzheimer’s and the risk for carriers remains high, although physicians suggest that with a healthy lifestyle can help. “This is a real problem,” said Middleton. “Genetic test companies say they offer advice about counselling but that usually proves to be a YouTube video outlining your own risks. Affected people needed one-to-one counselling.”

For their part, gene evaluation companies say results about other and Alzheimer’s and Parkinson’s are hidden behind locks. A individual has to answer several questions to show they “really” need to open these and is advised of possible risks. But those precautions were dismissed by Middleton. “You know there is medical information about you online and so you will go and find it. It is human nature.”

Margaret McCartney, a GP and author of The Patient Paradox, agreed. “What worries me is the competitive way these tests are marketed. People are advised all of of the advantages but there is not any mention of the drawbacks. The NHS is expected to mop those up.

“Meanwhile, the gene evaluation company has made its profit and walks away from the mess they’ve created. I believe that is immoral. They should be made to pay for counselling for their customers.”
