- Common name
- catalase
- Description
- This gene encodes catalase, a key antioxidant enzyme in the bodies defense against oxidative stress. Catalase is a heme enzyme that is present in the peroxisome of nearly all aerobic cells. Catalase converts the reactive oxygen species hydrogen peroxide to water and oxygen and thereby mitigates the toxic effects of hydrogen peroxide. Oxidative stress is hypothesized to play a role in the development of many chronic or late-onset diseases such as diabetes, asthma, Alzheimer's disease, systemic lupus erythematosus, rheumatoid arthritis, and cancers. Polymorphisms in this gene have been associated with decreases in catalase activity but, to date, acatalasemia is the only disease known to be caused by this gene. [provided by RefSeq, Oct 2009]

Significant/Non-significant: 0/3
Study 1
- Longevity Association
- Non-significant
- Population
- Danish
- Study Design
- The -262C/T polymorphism was examined in 2223 Danish individuals aged 45-93 years
- Conclusions
- The -262C/T polymorphism was not associated with survival

Study 2
- Longevity Association
- Non-significant
- Population
- Italian (Southern)
- Study Design
- A two-stage case-control study was performed to identify the association between longevity and variation of in homeostasis regulation pathway genes. 317 SNPs in 104 genes were analyzed in 78 cases (≥90 years, median age 98 years, 42 females) and 71 controls (<90 years, median age 67 years, 32 females) in stage 1. Then, 31 candidate SNPs identified in stage 1 (π markers = 0.1) were analyzed in an independent sample composed by 288 cases (≥90 years, median age 92 years, 163 females) and 554 controls (<90 years, median age 67 years, 277 females).
- Conclusions
- After adjustment for multiple testing, no significant association was identified between various SNPs and longevity.

Study 3
- Longevity Association
- Non-significant
- Population
- Danish
- Study Design
- 38 genes (311 SNPs) belonging to pro-antioxidant pathways were investigated for the association with physical and cognitive performances in a Cohort of 1089 Danish nonagenarians. For each gene analyzed in the pro-antioxidant pathway, the influence on longitudinal survival was tested.
- Conclusions
- No gene found associated with a functional phenotype showed a corresponding association with survival in the whole cohort. NDUFS1, TXNRD1, SOD2 and UCP3 were found significantly associated with lifespan in the female cohort. No association with survival was reported in males for genes belonging to the pro-oxidant pathway here analyzed.
