Somatic Mutation Analysis in Spaceflight: NASA Twins Genome Study

The NASA Twins Genome Study investigates the effects of spaceflight on somatic mutation accumulation by comparing genome-wide sequence data from a spaceflight astronaut and his Earth-bound twin. Utilizing advanced computational software on high performance computers, this study identifies and maps somatic mutations, with implications for understanding spaceflight-associated health risks, including cancer, neurodegeneration, and cardiovascular disease. The findings aim to bridge rodent and human space research, offering insights into tissue-specific pathophysiology, risk models, and potential therapeutic interventions.
