LongevityMap variant group
Entry Details
- Longevity Association
- Non-significant
- Population
- Spanish
- Study Design
- Three most common alleles of the APOE gene were examined in three cohorts (Spanish, Italian and Japanese) to study their association with longevity.
- Conclusions
- E4 allele was negatively associated with longevity in three cohorts, while the E2 allele was positively associated in Italian and Japanese cohorts.

- Common name
- dihydrolipoamide branched chain transacylase E2
- Description
- The branched-chain alpha-keto acid dehydrogenase complex (BCKD) is an inner-mitochondrial enzyme complex involved in the breakdown of the branched-chain amino acids isoleucine, leucine, and valine. The BCKD complex is thought to be composed of a core of 24 transacylase (E2) subunits, and associated decarboxylase (E1), dehydrogenase (E3), and regulatory subunits. This gene encodes the transacylase (E2) subunit. Mutations in this gene result in maple syrup urine disease, type 2. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

- Aliases
- E3; LAD; DLDD; DLDH; GCSL; PHE3
- Common name
- dihydrolipoamide dehydrogenase
- Description
- This gene encodes a member of the class-I pyridine nucleotide-disulfide oxidoreductase family. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. In homodimeric form, the encoded protein functions as a dehydrogenase and is found in several multi-enzyme complexes that regulate energy metabolism. However, as a monomer, this protein can function as a protease. Mutations in this gene have been identified in patients with E3-deficient maple syrup urine disease and lipoamide dehydrogenase deficiency. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]
