SNP information (chromosome, position, reference, and alternative) was based on the outputs of the Michigan Imputation Server. Column_title: Description Chromosome: SNP chromosome Positon: SNP genomic coordinate based on GRCh37 / hg19 Reference: Reference allele Alternative: Alternative allele Genotype_CAG_based_continuous_phenotype_analysis_pvalue: P-value in continuous phenotype analysis using residual age at onset based on genotyping CAG Genotype_CAG_based_dichotomous_phenotype_analysis_pvalue: P-value in 30% dichotomous phenotype analysis based on genotyping CAG Uninterrupted_CAG_based_continuous_analysis_pvalue: P-value in continuous phenotype analysis using residual age at onset based on uninterrupted CAG Uninterrupted_CAG_based_dichotomous_phenotype_analysis_pvalue: P-value in 30% dichotomous phenotype analysis based on uninterrupted CAG
