The importance of incorporating drug-drug interactions and lifestyle factors in pharmacogenomics-guided medication management for patients with major depressive disorder in a randomized controlled trial
Sep 2023
In this study, drug-drug interactions accounted for 32% of all IDgenetix-guided drug recommendations, and lifestyle factors accounted for 11%. Incorporating these non-genetic factors in IDgenetix testing significantly impacts the number of drug recommendations and improves remission rates in patients with moderate to severe depression.

Incorporation of the 40-gene expression profile (40-GEP) test to improve treatment decisions in high-risk cutaneous squamous cell carcinoma (cSCC) patients: case series and algorithm
May 2023
Cutaneous squamous cell carcinoma (cSCC) has become a significant public health issue due to its rapidly rising incidence and an estimated 1.8 million newly diagnosed cases annually. As with other cancers, treatment decisions for patients with cSCC are based primarily on a patient’s risk for poor outcomes.
