Until recently, only apolipoprotein E (APOE) polymorphisms have been found to correlate with late-onset (nonfamilial) Alzheimer disease (AD); however, these account for less than 50% of the VG. New GWA studies have found a chromosome 12 risk locus
What method will likely be used by AD researchers going forward? A) assessment of chromosome 12 for areas of linkage disequilibrium for AD B) association of APOE alleles with chromosome 12 SNPs C) sequencing of candidate genes on chromosome 12 and search for sequence similarity D) genotyping of a large cohort of AD patients and matched controls using a microchip E) analysis of genotypes of a large number of AD patients who have none of the expected APOE alleles
