rs3803304 is an intronic SNP in the AKT1 gene.
rs3803304 was significantly associated with longevity in a meta-analysis across three cohorts (odds ratio 0.78, CI: 0.68-0.89, adjusted p=0.043). An inverse association towards longevity was seen in those homozygous for the minor allele, with these subjects being underrepresented among long-lived (≥92 years old) cases (OR=0.41-0.5, p=0.00016). No significant association was seen in heterozygous subjects, suggesting a recessive pattern of effect. The authors postulate that rs3803304's effects may result from disruptions with an RNA regulatory mechanism, based upon its close proximity to a conserved exon-intron boundary in an area of high predicted regulatory potential.
