Rs3758391

rs3758391, a SNP in the SIRT1 gene, has been reported to potentially have some role in either longevity, or with higher statistical significance, better cognitive function in older individuals. SIRT1 is thought to regulate neuronal metabolism and survival in response to stress, and the equivalent gene in other species influences maximal life span. The study reporting improved cognition for carriers of rs3758391(T) alleles was based on over 1,000 Finnish adults over the age of 85, and a weak trend towards lower cardiovascular disease was also reported for this allele.
