A curated database of genes associated with dietary restriction in model organisms either from genetic manipulation experiments or gene expression profiling.
Genome-wide association study in 403 unrelated nonagenarians from long-living families and 1670 younger controls. Strongest candidates were then investigated in a meta-analysis of 4149 nonagenarian cases and 7582 younger controls.
Conclusions
No SNP reached significance in the GWAS but 62 SNPs had an indicative association with survival into old age. Of these 62 SNPs then studied in the meta-analysis, only one was significant: rs2075650 located in TOMM40 and close to APOE. This association may be due to linkage disequilibrium with rs429358 and rs7412 in APOE; both rs429358 and rs7412 were associated with longevity in the meta-analysis.
The protein encoded by this gene is a major apoprotein of the chylomicron. It binds to a specific liver and peripheral cell receptor, and is essential for the normal catabolism of triglyceride-rich lipoprotein constituents. This gene maps to chromosome 19 in a cluster with the related apolipoprotein C1 and C2 genes. Mutations in this gene result in familial dysbetalipoproteinemia, or type III hyperlipoproteinemia (HLP III), in which increased plasma cholesterol and triglycerides are the consequence of impaired clearance of chylomicron and VLDL remnants.

The protein encoded by this gene is localized in the outer membrane of the mitochondria. It is the channel-forming subunit of the translocase of the mitochondrial outer membrane (TOM) complex that is essential for import of protein precursors into mitochondria. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Aug 2015]
