Real-World Needs for Genetic Testing Reference Materials

From troublesome mutations to FDA validation studies

“Happy families are all alike; every unhappy family is unhappy in its own way.”

I have always thought the opening of Anna Karenina applies for many things beyond familial harmony (or lack thereof).  Certainly, in the world of molecular genetic diagnostics, conclusive results are usually obtained for most patients; however, there are times when a final result is more elusive than conclusive.  When this occurs, it may seem as though no two challenges are ever the same.

The following are real examples – presented in general terms for patient and institutional confidentiality – of difficult, unanticipated, and even bizarre cases I encountered during my time in clinical testing for predisposition to hereditary disease.  Each of these situations required extraordinary effort, dedicated time, and additional resources for resolution.  At the end of each day, satisfaction came from knowing that another problem solved was another patient helped in making life-altering medical management decisions.

Highlights from the Precision Medicine World Congress

Status of FDA regulation of laboratory developed tests, the promise of precision medicine, and a workshop about achieving accurate NGS laboratory test results

Posted by Russell Garlick on Feb 15, 2017 1:30:00 PM

On January 23-25, 2017 the Precision Medicine World Congress was held in Mountain View, California. The PWMC conference kicked off with Dr. Keith Yamamoto, Vice Chancellor for Science and Policy and Strategy UCSF, with Dr. Robert Califf, FDA Commissioner in a “fireside chat” format. Dr. Califf has been with the FDA for 2 years, has served as Commissioner for 11 months, but has resigned as of January 20th 2017. One of his important parting thoughts presented was how the FDA has been re-energized by the 21st Century Cures Act to hire new scientific talent to implement the President’s Precision Medicine and Cancer Moonshot plans.
