We were unable to detect an association between Val66Met status and MRLMD, regardless of APOE genotype. CONCLUSIONS: Our results suggest that within the cerebellum, decreased BDNF mRNA transcript may be mediated through the Val66Met mutation. Effects of the polymorphism on AD risk appear to be dependent on APOE-ε4 genotype, but age of AD onset appears to be earlier in carriers of the minor allele. We did not detect an association between Val66Met status and cognitive performance as measured by MRLMD.Disclosure: Dr. Burgess has nothing to disclose. Dr. Carrasquillo has nothing to disclose.
