Aging has a genetic component which is estimated to be over 25%. Different individuals age with a different pace even if they have a similar lifestyle. The reason for this is that the genetic changes that differentiate an individual in specific genetic locations change the aging program or render an individual more resistant against damages and age-related diseases.

As the cost for genomic sequences falls the genetic markup underlying human longevity is becoming unraveled, there is a urgent need to utilize the knowledge on genetic variants that influence the speed of aging.

The simplest form of such variants are Single-Nucleotide Polymorphism (SNPs). Association to longevity can be identified either via high throughput Genome wide Association Studies (GWAS) or via focused candidate gene approaches.


Study Identifications

We designed a Boolean expression for paper identification. We use an inclusive policy which means positive as well as negative studies are included.

Database Design

Each genetic variant investigated in a study is a data record, which has defined polymorphism and a genomic location. If the polymorphism is within or next to a gene it is linked to the respective genetic factor. Further a record of a polmorphism has an informal description as well as association specific information such as the ethnicity, age of cases (mean) and shorter lived allele. Further statistical data like number of cases/controls in the initial and replication studies, odds-ratio, p-value and whether it is significant are also included, if available. Moreover the utilized technology (e.g. PCR) and the type of study (GWAS, candidate gene). We strictly provide references to the primary information.
