Genetic disorders: empowering patients and families through information

12 June 2017 - by Arti Patel

'I've got the diagnosis, now what?' is one of the first questions families ask when they contact us at Unique, the UK-based organisation for rare chromosome and genomic disorders... [Read More]

GIANT makes short work of height gene discovery

20 February 2017 - by Professor Darren Griffin

A recent large-scale study that discovered 83 rare genes related to human height reveals the power of so-called genome-wide association studies... [Read More]

Combined genetic tests could aid autism diagnosis

07 September 2015 - by Dr Ashley Cartwright

Scientists have found that two genetic analysis techniques can increase the number of causative mutations found in children with autism spectrum disorder... [Read More]

Ancestral humans had more DNA

17 August 2015 - by Isobel Steer

Compared to ancestral humans, most modern people have lost 40.7 million base pairs of DNA... [Read More]

Genetic switch left 'on' linked to autism

Researchers in the United States have demonstrated how a gene mutation can contribute to a particular form of autism... [Read More]

Chromosomes play active role in cell division

20 July 2015 - by Meghna Kataria

A study has shown that chromosomes, far from being passive participants as had been assumed, are actively involved in the process of cell division... [Read More]

Autism study identifies extensive gene pattern

10 June 2013 - by Siobhan Chan

A large, complex gene network in people with autism has been identified by researchers at the University of Oxford... [Read More]

Twenty-five genetic variants for autism discovered

21 January 2013 - by Dr Victoria Burchell

Rare genetic variants may have a significant impact on a person's risk of developing autism, research suggests... [Read More]

The Irish are different - genetically

13 September 2010 - by Dr Rachael Panizzo

The genome of an Irish man has been fully sequenced for the first time, and reveals a unique 'Irish genetic signature'. Professor Brendan Loftus from the Conway Institute at University College Dublin, who led the study, hopes that the findings will contribute to the understanding of genetic diversity... [Read More]

Rare genetic variants found to play role in development of autism

14 June 2010 - by Sandy Starr

Results from the largest international study of its kind into autism strongly suggests that rare genetic variants contribute far more than common variants to the risk of developing the condition.... [Read More]

Study finds new genetic link to schizophrenia

17 May 2010 - by Victoria Kay

Genetics of leukaemia relapse revealed

01 December 2008 - by Dr Charlotte Maden

Scientists have uncovered key genetic changes in the cancer-causing cells when childhood leukaemia recurs. It is hoped that the findings can be used to help beat the disease. Acute lymphoblastic leukaemia (ALL), a cancer of the blood and bone marrow, is the most common form of childhood... [Read More]

New findings may transform hunt for schizophrenia genes

31 March 2008 - by Ailsa Stevens

Two independent studies published in the journal Science this week suggest that many rare gene mutations may be responsible for causing schizophrenia, challenging the widely held theory that combinations of several relatively common mutations are to blame. The researchers found that very rare genetic disruptions, often unique... [Read More]

Double dose of genes linked to learning difficulties

04 February 2008 - by Stuart Scott

Australian researchers have announced the identification of two genes that are involved in learning difficulties. Over 10,000 children born in the UK every year are affected by some form of developmental delay, but in 80 per cent of cases doctors are unable to determine a cause. Reporting... [Read More]

New project aims to read 1000 human genomes

27 January 2008 - by Dr Jess Buxton

An international project to read the entire genetic code of at least 1000 individuals will result in a comprehensive catalogue of human variation that will accelerate efforts to identify genetic factors involved in health and disease, scientists announced last week. The '1000 Genomes Project' will take... [Read More]

Chromosome abnormality linked to autism

14 January 2008 - by Ailsa Stevens

Researchers from the Boston-based Autism Consortium have discovered a rare chromosomal abnormality reported to be 100 times more common in children with autism. The study, published last week in the New England Journal of Medicine, found that in approximately 1 per cent of autism cases a small... [Read More]

Missing genes linked to autism

26 March 2007 - by Dr Jess Buxton

Many cases of autism could be linked to spontaneous genetic changes that result in large chunks of missing DNA, according to a new US study. The research, published early online in Science, shows that so-called 'copy number variants' could be an important factor in the appearance... [Read More]

More variation discovered in our DNA

27 November 2006 - by Dr Laura Bell

New research from 13 different research centres in Britain and the US has revealed an unsuspected amount of variation between each individual's DNA. The research, published simultaneously in the journals Nature, Nature Genetics and Genome Research gives a much more comprehensive picture of human genetic variation... [Read More]

UK's first 'parthenotes' created

10 September 2005 - by BioNews

A team of scientists from the Roslin Institute in Edinburgh, Scotland, has created the UK's first parthenogenic embryos, or 'parthenotes'. Using parthenogenesis - a Greek word that means 'virgin birth' - the research team were able to create embryos without the need for fertilisation of an egg by sperm. The Roslin team... [Read More]
