OBJECTIVES
The only locus
unequivocally associated with late onset Alzheimer's disease (AD) risk
is APOE. However, this locus accounts for
less than half the genetic variance. A recent study suggested that the
A allele of the 3'UTR biallelic polymorphism in the
LBP-1c/CP2/LSF gene was associated with reduced AD risk. Samples were diagnosed predominantly by clinical rather than pathological criteria. We have
sought to replicate this finding in a series of necropsy confirmed,
late onset AD cases and non-demented controls.
METHODS
The 3'UTR polymorphism in
the
LBP-1c/CP2/LSF
gene was typed in 216 necropsy confirmed AD cases and 301 non-demented
controls aged >73 years.
RESULTS
We found different
LBP-1c/CP2/LSF
allele distributions in our AD cases and controls (p=0.048); the A
allele was associated with reduced AD risk. The allele and genotype
frequencies observed in our cases and controls were similar to those
previously reported. No significant effects
emerged when the data were adjusted for age, sex, or apoE
4 carrier status.
CONCLUSIONS
Our data support
LBP-1c/CP2/LSF
as a candidate gene/risk factor for AD and provide justification for
future studies to investigate the role of this gene in Alzheimer's disease.
