The relationship between genetic variations of single nucleotide polymorphism (SNP) and brain imaging quantitative traits (QTs) is integral in the understanding of Alzheimer’s Disease (AD). Genome-wide association studies (GWAS) is useful in identifying SNP values as risk factors of developing AD; however, there are still more ways to analyze GWAS results through longitudinal analysis as well as multivariate analysis. In this project, I focused on visualizing GWAS results through PLINK and MultiPhen in R.
