Dataset Summary

This dataset contains summary statistics for 1,000 genomic variants associated with Alzheimer's disease. Each row represents a single-nucleotide polymorphism (SNP) mapped to the hg19 reference genome.

Dataset Structure

—Number of variants: 1,000
—Genome build: hg19

Data Fields

Based on the header of variants.csv:

Column	Type	Description
`snpid`	string	Unique identifier in `chr:pos_ref_alt` format
`chrom`	string	Chromosome (e.g., `chr6`)
`pos`	int	Genomic position (hg19)
`alt`	string	Alternate allele (effect allele)
`ref`	string	Reference allele (non-effect allele)
`rsid`	string	Reference SNP cluster ID
`pval`	float	P-value of the association
`beta`	float	Regression coefficient (effect size)
`se`	float	Standard error of the beta
