LongevityMap Gene

Gene details

HGNC symbol: ERCC2
Aliases: EM9; TTD; XPD; TTD1; COFS2; TFIIH
Common name: ERCC excision repair 2, TFIIH core complex helicase subunit
Description: The nucleotide excision repair pathway is a mechanism to repair damage to DNA. The protein encoded by this gene is involved in transcription-coupled nucleotide excision repair and is an integral member of the basal transcription factor BTF2/TFIIH complex. The gene product has ATP-dependent DNA helicase activity and belongs to the RAD3/XPD subfamily of helicases. Defects in this gene can result in three different disorders, the cancer-prone syndrome xeroderma pigmentosum complementation group D, trichothiodystrophy, and Cockayne syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

Study 1

Longevity Association

Population

Study Design

Analysis was performed in 149 centenarians (mean age 101.1 years old) and in 413 young subjects (mean age 27.1 years old).

Conclusions

The distribution of the Lys751Gln genotypes differed significantly between these groups (P = 0.017). In centenarians, the homozygous genotypes AA and CC were found less frequently than in young controls (29 vs. 36%, OR = 0.71, and 14 vs. 20%, OR = 0.652, respectively). The Arg156Arg and Asp312Asn were not significantly associated with extreme longevity.

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: 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.
