This report outlines the contributions of European countries to the Genomic Data Infrastructure (GDI), specifying the expected number of samples, the mix of legacy Whole Genome Sequences (WGS) and new DNA samples, sequencing technologies used, and the infrastructure for managing, storing, and sequencing these samples. Work AccomplishedBelow we detail the potential national legacy contributions to the GDI. The work was done with collaboration with the Genome of Europe - initiative (GoE) utilising its questionnaire with comparison to previously collected data. This was done partly for the reason to avoid overlapping sets of questions being sent to the same people during the same time period which probably would have decreased the response frequency for both related efforts. Data from 27 European countries has been aggregated, while only two countries provided no answers for the GoE questionnaire. These contributions include both legacy WGS, which some of may require reconsenting, and potential newly collected DNA or to be collected samples specifically for 1+MG and GoE. The report highlights the use of both short-read and long-read sequencing technologies across different countries, with work involving a range of biobanks, research institutes, and academic institutions. The capacities for sequencing and data processing vary, with some countries outsourcing these tasks due to limited local capacity.
