Scope
The Genotype Harmonization WG will ensure the availability of high quality genotype datasets harmonized across all PRIMED Consortium studies. This WG will address harmonization of both individual-level genotype data and genomic summary results. An initial priority for this WG will be to inventory existing data and formulate a quality control (QC) and harmonization plan. This plan will cover study-specific variant and sample QC; cross-study genotype harmonization -- including imputation to a common reference panel and transformation to a common genome build, allele representation, and data format; and cross-study QC to evaluate harmonization. Genotype QC and harmonization workflows will be implemented on the AnVIL or other platforms.
