The Exome Aggregation Consortium (ExAC) is a database of 60,706 unrelated individuals sequenced as part of various disease-specific and population genetic studies. There is partial overlap between ExAC and 1000 Genomes (1KG) (1,851 of the 2,504 samples in 1KG) and the Exome Sequencing Project (ESP) (3,936 of the 6,500 samples in ESP).
