}} in all 4 ind. samples (1699 total indv.) associated with immediate recall, minor allele (C) carriers displayed worse short-term [[memory]] performance in a per allele fashion

per HapMap data, the haplotype containing the C allele is in high LD with a (23andMe covered) haplotype consisting of [[rs4667867]](A) (r^2 = 1), [[rs13421166]](C), [[rs2126152]](T), [[rs6432860]](A) (+ the annotated SNP [[rs3812718]](C) ) in the CEU+TSI sample
