Coronavirus: Genetic study assesses effect on different people

Researchers are to study the genetic codes of severely-ill Covid-19 patients to find out why the disease affects some people more than others. The Edinburgh University-led programme will identify the specific genes that cause a predisposition to the disease. It will allow the genome sequencing of up 20,000 people who have been in intensive care […]

Lilly drug for cancers with highly targetable genetic abnormality gets FDA nod

The Food and Drug Administration has granted accelerated approval to the latest in a growing group of cancer drugs designed to target genetic abnormalities with a high probability of producing a clinical effect. The agency granted the accelerated approval Friday to Indianapolis-based drugmaker Eli Lilly’s Retevmo (selpercatinib) for advanced non-small cell lung cancer (NSCLC) and […]

Coronavirus to be tracked using its genetic code

Scientists are to track the spread of the coronavirus in the UK by using clues in its genetic code. Analysing samples collected from patients will also reveal whether the virus is mutating into new strains. There have been more than 5,600 laboratory-confirmed cases in the UK so far, but the true figure is far, far […]

Prime editing: DNA tool could correct 89% of genetic defects

A new way of editing the code of life could correct 89% of the errors in DNA that cause disease, say US scientists. The technology, called prime editing, has been described as a “genetic word processor” able to accurately re-write the genetic code. It has been used to correct damaging mutations in the lab, including […]

Genetic tests: Experts urge caution over home testing

People should not make health decisions based on genetic tests they do at home, experts have warned. The University of Southampton team, writing in the British Medical Journal, warn results can be unreliable. The geneticists said the tests could be wrongly reassuring – or lead to unnecessary worry. 23andMe, one of the companies offering tests, […]

Breast cancer: Call for genetic screening for all

Offering every woman diagnosed with breast cancer genetic screening would save hundreds of lives each year, a study suggests. Currently, only those with risk factors such as a close family history of breast cancer are offered the check. Researchers say screening everyone would enable women to make informed treatment choices and allow family members to […]

Leamington father's dilemma over children's genetic cancer test

A father must wait years before he can find out if his three children carry the cancer gene that led to his wife’s death. Raj Singh Rainu’s 34-year-old wife Nim, from Leamington Spa, died in September after being diagnosed with aggressive stomach cancer in January 2018. Their three children, aged nine, five and three, have […]

I Got A Double Mastectomy After A Genetic Test. Then I Learned The Results Were Wrong.

I was 18 when I first heard Baz Luhrmann’s musical version of Mary Schmich’s essay “Wear Sunscreen.” I felt it had a special meaning in relation to my life, but at the time, I couldn’t pinpoint exactly how or why. It simply spoke to me. And, it turns out, the song’s lyrics — “the real […]

Haemochromatosis: 'Most common' genetic disorder test call

A woman who believes three members of her family died from the UK’s most common genetic disorder wants to see routine testing introduced. New research from Exeter University shows haemochromatosis could be causing serious health issues for 20 times more people than previously thought. Jenny Lees’ son Jason Cloke died in 2010 aged 42 after […]

World’s First Gene-Edited Babies Could Set Genetic Science Backward, Experts Worry

Ethicists and medical experts in the U.S. say that the use of gene editing to make babies resistant to HIV infection is a step too far ― and could be a step back for genetic science. News broke early Monday morning that Chinese scientist He Jiankui altered the genetic code of two embryos to make […]

Genetic Testing for Breast Cancer: Psychological and Social Impact

Thinking about getting a genetic test to find out if you have a mutation in one of the breast cancer susceptibility genes—BRCA1 or BRCA2? First, consider whether you're in the small minority of women for whom the test may be helpful. The psychological, emotional, and social implications of genetic testing also are worth considering, both […]

One-off genetic test could detect heart attack risk

People born at increased risk of heart attack could be identified by a one off-genetic test, a study has found. The Genomic Risk Score (GRS) test would only cost £40, cheap enough for population-wide screening, say the researchers. It could help to explain why people with apparently no conventional risk factors, such as high cholesterol, […]
