A gene is being identified by scientists whose mutation is linked to the development of an aggressive form of brain cancer.
An error in a gene called TCF12 is associated with more aggressive forms of a disease called anaplastic oligodendroglioma.
"Our in-depth study has set out many of the genetic defects that cause this rare but highly aggressive form of brain cancer - including identifying a gene mutation that appears in particularly fast-growing forms," said professor Richard Houlston at The Institute of Cancer Research, London.
The largest ever genetic study of oligodendrogliomas provides key insights into the causes of such aggressive form of cancers and how they might be treated.
Oligodendrogliomas are fast-growing cancers that account for around 5-10% of all tumors of the brain and central nervous system, and typically have a very poor prognosis.
In the study published in the journal Nature Communications, researchers identified mutations in the TCF12 gene in 7.5% of anaplastic oligodendrogliomas.
This subset of cancers grew more rapidly, and in other ways seemed more aggressive, than those where the gene was intact.
"Anaplastic oligodendrogliomas are difficult to remove by surgery and do not respond well to other forms of treatment. We hope this new information might be used to discover new targeted therapies, offering patients a better chance at survival from this aggressive cancer," Houlston said.
