LongevityMap variant

Entry Details

Longevity Association
Significant
Population
Ashkenazi Jewish, Czechs (Bohemian)
Study Design
525 Ashkenazi Jews composed of 216 probands (age ≥95 years) and 309 unrelated individuals (ages 51 to 94) were genotyped for the functional variant of KLOTHO, termed KL-VS. 435 elderly individuals (≥75 years) were genotyped.
Conclusions
A common variant of KLOTHO, the KL-VS allele, was associated with human longevity. A heterozygous advantage for longevity was observed for individuals ≥79 years of age (P<0.004).

Common name
klotho 
Description
This gene encodes a type-I membrane protein that is related to beta-glucosidases. Reduced production of this protein has been observed in patients with chronic renal failure (CRF), and this may be one of the factors underlying the degenerative processes (e.g., arteriosclerosis, osteoporosis, and skin atrophy) seen in CRF. Also, mutations within this protein have been associated with ageing and bone loss. [provided by RefSeq, Jul 2008]
