deCODE and Radboud Discovery in Bladder Cancer May Link Disease Risk and Somatic Mutations in Tumors
"This discovery is exciting because it offers us a truly unique window toa more holistic view of the genetic contribution to the pathogenesis of acommon form of cancer. This is compelling from the point of view oftherapeutic development. About half of all UBC cases are low grade andtreatment is usually successful. But the disease frequently recurs, whichmakes treatment costly and would make a drug that could reduce the need forinvasive procedures a valuable tool for patients and the healthcare system,"said Kari Stefansson, executive chairman and president of research at deCODEand senior author on the paper.
This is the fifth SNP linked to risk of UBC in multiple populations, andthe fourth discovered under the deCODE-Radboud collaboration. The studyanalyzed genotypic data from more than 50,000 patients and controls from adozen countries, and found that those who carry the 'T'version of thechromosome 4 SNP are at approximately 25% greater risk of developing UBC percopy carried than are non-carriers. The 5% of people who are at highest riskfrom this combination of five markers are at approximately 60% greater thanaverage risk of UBC. Since the average lifetime risk of UBC is about 4% formen in the United States, those with the highest risk constellation of thesemarkers would be at a roughly 6.5% risk of the disease. The study, 'Asequence variant at 4p16.3 confers susceptibility to urinary bladder cancer,'is published online today in Nature Genetics and will appear in an upcomingprint edition of the journal.
Urinary bladder cancer is estimated to be the 9th most common cancerworld-wide and the 13th most common cause of death from cancer. Every year,some 70,000 people in the United States are diagnosed with bladder cancer,and more than 14,000 people will die of the disease. Bladder cancer has beenlinked to exposure to various types of toxic substances such as cigarettesmoke and industrial chemicals. Incidence of bladder cancer variesconsiderably between ethnicities, and as the risk factors reported here werediscovered by analysing DNA from groups of European descent, it is our hopethat the publication of these findings will contribute to the swift analysisof the impact of these variants in cohorts of other continental ancestries.

Headquartered in Reykjavik, Iceland, deCODE genetics is a global leaderin analyzing and understanding the human genome. Using its unique expertiseand population resources, deCODE has discovered key genetic risk factors fordozens of common diseases ranging from cardiovascular disease to cancer.deCODE employs its capabilities to develop DNA-based tests and personalgenome scans to better understand individual risk and empower prevention. Italso licenses its tests, intellectual property and analytical tools topartners, and provides comprehensive genotyping, sequencing and data analysisservices to companies and research institutions around the globe. Through itsCLIA- and CAP-certified laboratory deCODE offers DNA-based tests for gaugingrisk and empowering prevention of common diseases, including deCODE T2(TM)for type 2 diabetes; deCODE AF(TM) for atrial fibrillation and stroke; deCODEMI(TM) for heart attack; deCODE ProstateCancer(TM) for prostate cancer;deCODE Glaucoma(TM) for a major type of glaucoma; and deCODE BreastCancer,for the common forms of breast cancer. Through its pioneering personal genomeanalysis service deCODEme(TM), deCODE enables individuals to betterunderstand their risk of dozens of common diseases and to learn about theirancestry and other traits.
