Precision or personalized medicine refers to a treatment paradigm in which genetics/genomic testing is integrated with traditional laboratory testing to aid in the diagnosis, treatment, and prevention of disease. Precision medicine has relevance for both common and rare diseases. The tools of precision medicine can be applied to many disciplines including diabetes and endocrine conditions. We aim to use combine modern genetic testing and molecular biology techniques with traditional methods of testing endocrine physiology. In particular, we take a “Bedside to Bench” approach. In doing so we find patients with rare or unique presentations of disease, perform genetic testing, and then take these results to the lab to perform functional testing.
