Apolipoprotein E (ApoE) gen has been found to confer risk for Alzheimer disease in every population studied. We are interested in analyzed the exonic variants and the promoter polymorphisms in our Canary population.
By means of PCR RFLP analysis of DNA from patients (NINCS ADRDA criteria) and controls (cognitive state CAMCOG test measured) we analyzed the known exonic and promoter polymorphism of ApoE gen.
We have found an association of Alzheimer disease risk based on exonic variants of ApoE gen, with a clear cut dose effect on susceptibility and no risk conferred by the promoter polymorphisms. Age at onset are not affected by variants of ApoE gen, and patients gender strongly modulate the disease susceptibility.
We have found in our Canary population an association between Alzheimer disease with exonic variants of ApoE gen with a strong modulation by the patients gender.
