careful attention to data quality has been appreciated for some time in this field, and a number of strategies for quality control and quality assurance(QC/QA) havebeen developed. Here we extend these methods and describe a system ofQC/QA for genotypic data in genome-wide association studies (GWAS). This system includes some new approaches that (1) Abstract. Summary: GWASTools is an R/Bioconductor package for quality control and analysis of genome-wide association studies (GWAS). GWASTools brings the interactive capability and extensive statistical libraries of R to GWAS. Data are stored in NetCDF format to accommodate extremely large datasets that cannot fit within R's memory limits. Genome Wide Association Studies What is a Genome Wide Association Study? What is a Genome Wide Linkage Study? Linkage vs Association (Risch and Merikangas 1996) Study Design Different methods for detecting association What is a Genome Wide Association Study? Goal Uncover the genetic basis of a given disease. Basic Idea A rather vague idea of a The following sections lead you through quality assurance procedures performed in genome-wide association studies to identify samples of poor quality (call rates, heterozygosity, etc.) and those whose identity is of question (mismatched gender, ethnicity different than intended for the study, cryptically related, etc.). Imputation and quality control steps for combining multiple genome-wide datasets. After imputing each study dataset, we attempted to merge all of the imputed datasets together to generate a mega-analysis ready dataset (combining all eMERGE sites together). The effect of genome-wide We searched PubMed with the terms "natural killer T cell lymphoma" OR "NK/T lymphoma" OR "NKTCL" in combination with "genome-wide association study" OR "GWAS" for articles published in any language up to Sept 11, 2018, in which genes associated with risk of NKTCL that were identified through genome-wide association studies Rigorous organization and quality control (QC) are necessary to facilitate successful genome-wide association meta-analyses (GWAMAs) of statistics aggregated across multiple genome-wide association studies. This protocol provides guidelines for [1] organizational aspects of GWAMAs, and for [2] QC at as the cost of failure is potentially huge for studies that are designed and executed with low statistical power and inadequate quality control.
