[PMID 18518926] - rs2227902 and rs3796530 were found to be in 100% LD with a variable number tandem repeat (VNTR) length variant in the REST gene in a sample of 746 elderly Caucasians. Minor alleles (T and A, respectively) at both locations associated with the 4-length VNTR, while common alleles associated with the VNTR 5-length repeat. Carriers of the 4-length VNTR homozygous for the Val66 variant in the BDNF gene performed slightly, but significantly (p = 0.004), better than those without in the general cognitive tests performed in the study. Carriers of the 5-length VNTR and the 66Met BDNF variant had significantly lower g (p = 0.01), but the effect was not as great as the individual effect of the 66Met allele.
