LongevityMap variant

Entry Details

Longevity Association: Non-significant
Population: Danish
Study Design: 592 SNPs from 77 genes involved in nine sub-processes were analyzed in 1089 long-lived and 736 middle-aged Danes. Then, a replicated study was carried out in a German cohort.
Conclusions: The results did not remain significant after correction. The findings drawn from the Danish cohort were not replicated in German samples.

Common name: telomerase reverse transcriptase
Description: Telomerase is a ribonucleoprotein polymerase that maintains telomere ends by addition of the telomere repeat TTAGGG. The enzyme consists of a protein component with reverse transcriptase activity, encoded by this gene, and an RNA component which serves as a template for the telomere repeat. Telomerase expression plays a role in cellular senescence, as it is normally repressed in postnatal somatic cells resulting in progressive shortening of telomeres. Deregulation of telomerase expression in somatic cells may be involved in oncogenesis. Studies in mouse suggest that telomerase also participates in chromosomal repair, since de novo synthesis of telomere repeats may occur at double-stranded breaks. Alternatively spliced variants encoding different isoforms of telomerase reverse transcriptase have been identified; the full-length sequence of some variants has not been determined. Alternative splicing at this locus is thought to be one mechanism of regulation of telomerase activity. [provided by RefSeq, Jul 2008]
