Abstract

BACKGROUND:

Previous linkage studies have shown that chromosome 12 harbors susceptibility genes for late-onset Alzheimer disease (LOAD). However, association studies of several candidate genes on this chromosome region have produced ambiguous results. A recent study reported the association between the glyceraldehyde-3-phosphate dehydrogenase (GAPD) gene on chromosome 12p and the risk of LOAD.

METHODS:

The authors conducted family-based and case-control association studies in two independent LOAD data sets on 12 single-nucleotide polymorphisms (SNPs) in the GAPD gene and its paralogs.

RESULTS:

No association was found of the GAPD gene with LOAD in the family-based data set, but marginal evidence of association was seen in the later-onset subgroup when age at onset was stratified. The SNP rs2029721 in one GAPD pseudogene was also found to be associated with risk for LOAD in the unrelated case-control data set (p = 0.003).

CONCLUSIONS:

The GAPD gene and its pseudogene may play a role in the development of late-onset Alzheimer disease. However, the effect, if any, is likely to be limited.
