About Bravo

This variant browser currently shows chromosome locations, alleles, VEP functional annotations, and allele frequencies for 463 million variants observed in 62,784 individuals sequenced in NHLBI's TOPMed program.

The information is shared by TOPMed Phase 1 and Phase 2 studies and is available for users that agree to the terms.

The sequencing analysis pipeline consists of two major processes:

  1. Harmonization of data from the BAM files provided by the sequencing centers and
  2. Joint variant discovery and genotype calling across studies.
The alignment pipeline is available at github.com/statgen/gotcloud.
