Key Takeaways
- Two genetic variants, BSN and APBA1, are associated with increased risk of obesity in adults.
- The rare BSN variants were found to increase the risk of developing type 2 diabetes and nonalcoholic fatty liver disease.
- Bassoon and APBA1 genes impact obesity by transmitting signals through brain cells, affecting appetite control.
- Obesity affects over 1 billion people worldwide, with significant health risks and implications for premature death.
- The discovery reveals a new biological mechanism for obesity, emphasizing the relationship between genetics, neurodevelopment, and obesity.

A recent study has identified two genetic variants that are linked to an increased risk of obesity in adults, shedding light on a new way the brain may play a role in obesity. These variants in the genes BSN and APBA1 were found to increase the risk of obesity, with the BSN gene variants specifically associated with an increased risk of developing type 2 diabetes and nonalcoholic fatty liver disease. Moreover, these findings challenge the notion that genetics only contribute to childhood obesity, as these variants are linked to obesity that occurs in adulthood.
The study suggests that the BSN and APBA1 genes may impact obesity by influencing the transmission of signals through brain cells and contributing to diseases that lead to brain degeneration. This discovery opens the door to a new biological mechanism for obesity, distinct from previously studied variants that impact appetite regulation through the leptin-melanocortin pathway. With over 1 billion people worldwide affected by obesity, these new insights highlight the significance of genetic factors in understanding and addressing obesity as a global health concern.
These genetic findings provide a fresh perspective on the relationship between genetics, neurodevelopment, and obesity, as stated by Giles Yeo, the lead researcher from Cambridge University's Metabolic Research Council. With obesity being a leading cause of preventable deaths and carrying significant health risks, understanding the genetic underpinnings of obesity has the potential to revolutionize prevention and treatment strategies.
Analysis
The identification of genetic variants BSN and APBA1 linked to increased obesity risk presents a breakthrough in understanding the brain's role in obesity. These findings challenge the misconception that genetics only contribute to childhood obesity, shedding light on a new biological mechanism for adult obesity. Short-term consequences may include increased focus on genetic factors in obesity research and potential implications for treatment strategies. Long-term implications could lead to the development of personalized preventive and treatment approaches. With over 1 billion affected by obesity globally, these insights underscore the significance of genetic factors and the potential for revolutionary changes in addressing obesity as a global health concern.
