WebJun 29, 2024 · Leveraging DNA methylation and SNP data from more than 40,000 individuals, we identify 137 genome-wide significant loci, of which 113 are novel, from genome-wide association study (GWAS) meta-analyses of four epigenetic clocks and epigenetic surrogate markers for granulocyte proportions and plasminogen activator … WebDec 22, 2024 · METAL is a tool for meta-analysis genomewide association scans. METAL can combine either (a) test statistics and standard errors or (b) p-values across studies (taking sample size and direction of effect into account). METAL analysis is a convenient alternative to a direct analysis of merged data from multiple studies.

WebApr 13, 2024 · Understanding the genetic basis of human complex diseases is increasingly important in the development of precision medicine. Over the last decade, genome-wide association studies (GWAS) have become a key technique for detecting associations between common diseases and single nucleotide polymorphisms (SNPs) present in a … WebA reference panel is required when analysing summary statistics. It is used to estimate the correlations between nearby predictors (the linkage disequilibrium). In most cases, the summary statistics will correspond to SNPs (i.e., contain the results from an association study that regressed the phenotype on each SNP individually). trackmaster productions 2016
