Why Genetic Information Should be a Trade Secret



This has been a hot topic thats doing rounds. Why should genetic information be a trade secret?

National health systems and insurers, regulators, researchers, providers and patients all have a strong interest in ensuring broad access to information about the clinical significance of variants discovered through genetic testing.

The whole question of proprietary claims over genetic information is not limited to patents and is very much open to debate.  In essence, the authors say that the Myriad patent saga serves as an excellent case study of the importance of collecting clinical data and the implications of keeping those data private. Myriad’s imminent entry into Europe presents an opportunity to implement policies on access to data on the mutation of the BRCA gene which leads to breast cancer. Such policies would set a salutary precedent not only for BRCA but for genetic testing in general, including whole-genome analysis. Mutations on single point mutations on active stretches of the gene are clearly deleterious because they disrupt protein function. Data on these mutations are valuable to those tested and to their health providers, influencing decisions about treatment options. But other data is being withheld, report the authors, which could be essential for further research in the analysis and treatment of cancer caused by single point variations. These are  ‘variants of unknown significance’ (VUS). They occur between the active and inactive segments of the gene and are therefore particularly difficult to interpret. The paper reports that Myriad claims that the fraction of cases resulting in a VUS is 3% in its hands, and 20% for most EuropeanBRCA-testing services.

Is It Anthrax or Just White Powder?

A good article about A microfluidic chip that rapidly identifies pathogens by scanning their genomes.

From the article :

When a patient is admitted to the hospital with signs of a dangerous systemic bacterial infection, or when a post-office worker finds white powder in a suspicious-looking envelope, the ability to quickly identify potential pathogens is important. To accomplish that, a team of Massachusetts researchers is developing a microfluidic chip that performs fast DNA sequencing to rapidly identify bacteria. The goal is a device simple enough to use in airport and other security screening.

In order to identify the bacteria in a blood sample or in a building's ventilation system, researchers or clinicians usually must start by coaxing it to grow in culture in the lab. This takes about 14 to 48 hours. In the meantime, a patient with a drug-resistant infection may be given the wrong antibiotic, or emergency medical workers may miss the signs of a potential bioterror attack.
