Glossary

CNV (copy number variation)

CNV (copy number variation) refers to a situation in which a person has multiple copies of a portion of DNA (often a gene). This can influence susceptibility to disease and other traits.

'Landmark' study could change future of breast cancer

23 April 2012 - by Dr Linda Wijlaars

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... [Read More]

Ten questions for Dr Julian Huppert MP

12 July 2010 - by Dr Vivienne Raper

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.

Gene clue to neuroblastoma

22 June 2009 - by Lorna Stewart

Neuroblastoma, a form of paediatric cancer which affects the nervous system, may be caused by copy number variations (CNVs) in genes which control nervous system development. The research, published last week in Nature, suggests a different genetic mechanism for cancers than was previously proposed. Dr John Maris who led the study at the University of Pennsylvania, Philadelphia, US, said 'We can infer that it's not just going to be true for neuroblastoma. My expectation is that there will be ...
