CNV (copy number variation)
CNV (copy number variation) refers to segments of DNA larger than 1kb (1000 base-pairs) that vary in copy number between individuals. CNVs that encompass one or more genes can influence susceptibility to disease and other traits.

DNA test for prostate cancer relapse shows promise
A DNA test for men with prostate cancer could indicate whether their cancer is likely to recur after treatment, and if so, how aggressively, say researchers from the University of Pittsburg School of Medicine, USA...
'Landmark' study could change future of breast cancer
Breast cancer can be reclassified into ten separate 'diseases' based on its genetic characteristics, according to scientists. Analysis of the DNA and RNA from almost 2,000 tumours identified ten genetically different subtypes of breast cancer with different survival outcomes. The information could be used to better predict the outcomes of the disease, as well as offer tailored treatment to patients...
Short people 'short' on genes
Short people can blame deleted sections of DNA for their diminutive stature, according to a study looking at variations in the genomes of over 12,000 children...
Rare gene mutation linked to schizophrenia
Scientists have identified a rare gene mutation which they believe is linked to schizophrenia. The researchers from the University of California, San Diego and Trinity College Dublin performed a genome-wide association scan...
Study finds new genes linked to anorexia
Several genetic markers associated with the psychiatric disorder anorexia nervosa (AN) have been identified. American researchers carried out the first, large-scale genome-wide association study (GWAS) for AN...
ADHD genetics is a complex issue, say experts
Last week researchers from Cardiff University published a study in the Lancet, where they claimed to have uncovered evidence of a genetic link to attention deficit hyperactivity disorder (ADHD)...

The Irish are different - genetically
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...
Ten questions for Dr Julian Huppert MP
Before Dr Julian Huppert was elected MP for Cambridge in May this year, he was a computational biologist at Cambridge University studying the structure and function of DNA. Now, he's one of only two scientists with PhDs in parliament. BioNews quizzed him about science funding, synthetic biology and the shortage of scientists in politics...
Rare genetic variants found to play role in development of autism
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....
