| Summary: | Abstract Background Genetic research on longevity has provided important insights into the mechanism of aging and aging-related diseases. Pinpointing import genetic variants associated with aging could provide insights for aging research. Methods We performed a whole-genome sequencing in 19 centenarians to establish the genetic basis of human longevity. Results Using SKAT analysis, we found 41 significantly correlated genes in centenarians as compared to control genomes. Pathway enrichment analysis of these genes showed that immune-related pathways were enriched, suggesting that immune pathways might be critically involved in aging. HLA typing was next performed based on the whole-genome sequencing data obtained. We discovered that several HLA subtypes were significantly overrepresented. Conclusions Our study indicated a new mechanism of longevity, suggesting potential genetic variants for further study.
