Two RNA studies give clues to neurodegeneration

23 January 2012 - by Dr Zara Mahmoud

Two independent studies have suggested new targets for treating neurodegenerative diseases...[Read More]

Statins could treat breast cancer gene mutation

23 January 2012 - by Ruth Saunders

Mutations in a single gene could be used to identify breast cancer tumours that can be tackled with cholesterol-lowering statins, a recent study has found. Scientists identified a link between a cholesterol-building mechanism in the body and disorganised cell growth indicative of cancer...[Read More]

Myriad Genetics acquires patent on another breast cancer-linked gene

23 January 2012 - by Ayesha Ahmad

Myriad Genetics, a leading US molecular diagnostic company, has been granted exclusive rights to an analysis of the RAD51C gene. Mutations of the gene have been associated with an increased risk for hereditary breast and ovarian cancer and the company now hopes to develop a commercial test for RAD51C....[Read More]

Gene link to oesophageal cancer

23 January 2012 - by Ayesha Jadoon

The gene causing a skin disorder which predisposes to oesophageal cancer has been identified. More than nine out of ten people with tylosis, which causes thickening of the skin on the palms and soles, will develop oesophageal cancer before the age of 65, but until now the reason for this was obscure...[Read More]

£5.8m boost for mitochondrial disease research

23 January 2012 - by Maria Botcharova

An experimental genetic technique to prevent serious diseases from passing between mother and child is to receive £5.8 million funding. The Wellcome Trust is contributing £4.4 million to the new Centre for Mitochondrial Research at Newcastle University...[Read More]

'High risk' prostate cancer gene found

16 January 2012 - by Linda Wijlaars

A rare gene variant that could increase the risk of prostate cancer has been identified by researchers in the USA. Although the variant accounts for only a small fraction of all prostate cancers, the study found it was more common in men with an inherited form of the cancer and in those who are diagnosed before the age of 55...[Read More]

Book Review: Perfect People

14 November 2011 - by Dr Amy Strange

If you could design your child right down to the smallest detail, what characteristics would you pick? This is the choice that Dr and Mrs Klaesson face in Peter James' latest novel, when they visit Dr Dettore, a renegade scientist who offers couples designer babies...[Read More]

Aspirin cuts hereditary bowel cancer risk by 60 percent

31 October 2011 - by Suzanne Elvidge

Taking a daily aspirin has been recommended for people with a high risk of an inherited form of bowel cancer. Results published in The Lancet suggested the risk for those with Lynch syndrome could be cut by 63 percent...[Read More]

Race and genetics in stem cell transplantation

17 October 2011 - by Professor Steven Marsh

Each year around 2,800 people in the UK have a stem cell transplant, without which they would have shortly faced death, usually from a blood cancer or another blood disorder. The race of a patient is a real factor in how likely they are to match with a donor....[Read More]

Female fertility may be improved by breast cancer risk gene

17 October 2011 - by George Frodsham

A genetic mutation known to increase a woman's risk of cancer could also increase their fertility, research suggests. Women with mutations in the BRCA1 or BRCA2 genes, which are associated with a higher risk of breast and ovarian cancer, were found to have larger families when compared to control groups...[Read More]

Severe hypoglycaemia linked to mutation in insulin signalling gene

10 October 2011 - by Tamara Hirsch

Mutations in a single gene have been identified as the cause of a severe and life-threatening form of hypoglycaemia...[Read More]

Dead end for the 'longevity gene'?

03 October 2011 - by Louisa Petchey

A gene associated with increased lifespan in a number of organisms is now thought to have no effect on longevity after a second look revealed significant flaws in the original studies on which the assumptions were based. The findings will disappoint the manufacturers of many anti-ageing creams that claim to work by activating the gene, but are unlikely to put a stop to research...[Read More]

Book Review: My Beautiful Genome - Exposing Our Genetic Future One Quirk at a Time

Same genetic mutation linked to ALS and dementia

26 September 2011 - by George Frodsham

Researchers have identified a strong link between a genetic fault and two common neurological disorders. Two independent studies have found that the mutation is common in patients with amyotrophic lateral sclerosis (ALS) and patients with frontotemporal dementia (FTD), particularly if the disease is familial...[Read More]

Safeguarding consent and confidentiality in clinical genetic practice

26 September 2011 - by Professor Anneke Lucassen and Alison Hall

Suppose you have just had a genetic test for a condition that you suspect runs in your family. Aside from the possible implications for your own health, could – or should – your results be used to help to interpret tests done on other members of your family?...[Read More]

Gene therapy to treat HIV shows promise

26 September 2011 - by Louisa Petchey

The success of a new gene therapy trial represents a significant step towards a 'functional cure' for HIV, US researchers announced this week. By mimicking the effects of a naturally occurring gene mutation that makes an individual resistant to infection, this therapy aims to reduce or eliminate the dependency of HIV patients on antiretroviral drugs....[Read More]

Book review: Ethical and Legal Requirements for Transnational Genetic Research

26 September 2011 - by Professor Sandy Raeburn

First, here is the bad news. Readers attracted by this title are in for a stormy and depressing journey. The writing, both in choice of language and sentence construction, is turgid. The problems of 'plain English' start in the six-page introduction, reach a low point in the ethical chapter and only improve slightly in the legal section...[Read More]
