An important milestone has been reached for the 1000 Genomes project – some of the samples that were collected have been re-sequenced to improve the quality and sequencing depth of the data. Sequence data were generated from 2,504 samples collected for the 1000 Genomes project phase 3 panel set. The samples were sequenced to 30x coverage and aligned to the GRCh38 human reference genome sequence. The data are publicly available to the research community and can be accessed from The International Genome Sample Resource (IGSR) website.
