Welcome to GenAge, the benchmark database of genes related to ageing. GenAge is divided into genes related to longevity and/or ageing in model organisms (yeast, worms, flies, mice, etc.) and ageing-related human genes. The section on human ageing-related genes includes the few genes directly related to ageing in humans plus the best candidate genes obtained from model organisms. Human genes are thus considerably better annotated and include more information. GenAge is manually curated by experts to ensure high-quality content.
