The sex-specific effect of the apolipoprotein E allele and methylenetetrahydrofolate reductase gene polymorphism on the biochemical, anatomical, and cognitive profiles of patients clinically diagnosed with probable Alzheimer's disease.

We demonstrated the sex-specific effect of the APOE allele and MTHFR polymorphism on the serological and anatomical biomarkers in AD patients. The APOE allele and MTHFR mutations did not directly affect cognitive progression, but differentially affected other biochemical factors, between the sexes. These findings will aid in devising novel preventive and therapeutic strategies.
