% July 17, 2017
This archive contains 1 files:
vitd.gwama.out
This file provides genome-wide meta-analysis summary statistics from GWAMA for standardized log-transformed 25 hydroxy vitamin D levels.
In addition to GWAS quality filtering, such as imputation quality and Hardy-Weinberg equilibrium, variants were retained if MAF>=0.005.
