HuGENet™ Workshops

Strengthening the Reporting of Genetic RIsk Prediction Studies (GRIPS) HuGENet Workshop

The rapid and continuing progress in gene discovery for complex diseases is fueling interest in the potential application of genetic risk models for clinical and public health practice. The number of studies assessing the predictive ability is steadily increasing, but the quality and completeness of reporting varies. A multidisciplinary workshop sponsored by the Human Genome Epidemiology Network (HuGENet™) developed a checklist of 25 items recommended for strengthening the reporting of Genetic RIsk Prediction Studies (GRIPS), building on the principles established by prior reporting guidelines such as the STrengthening the REporting of Genetic Association Studies (STREGA) initiative.

These recommendations aim to enhance the transparency of study reporting, and thereby to improve the synthesis and application of information from multiple studies that might differ in design, conduct, or analysis. The GRIPS Statement and Explanation and Elaboration papers were published simultaneously in multiple journals in March 2011, including the Annals of Internal Medicine, PLos Medicine, BMJ, Circulation: Cardiovascular Genetics, European Journal of Clinical Investigation, European Journal of Epidemiology, European Journal of Human Genetics, Genetics in Medicine, Genome Medicine, and Journal of Clinical Epidemiology.

HuGENet™ is a global initiative committed to the development and integration of the knowledge base on human genetic variants & health.
