About this display
LYFE Sciences is an independent, unfunded variant interpretation tool. This page displays population frequency data from gnomAD Canada v1.0; I did not generate, fund, or contribute to this dataset. All data belongs to the gnomAD Canada project and the HostSeq cohort. I am presenting it in a convenient format alongside variant interpretation.
Data source
All population frequency data on this page originates from gnomAD Canada v1.0, produced from the HostSeq whole-genome sequencing cohort and made publicly available by the BC Genome Sciences Centre (BCGSC). The official gnomAD Canada browser is at gnomad.ca and the BCGSC instance at bcgsc.ca/gnomad. Please cite the original resource if you use this data in research.
Population labels
Population ancestry labels are reproduced exactly as provided by gnomAD Canada and the HostSeq cohort. These labels reflect ancestry inference using gnomAD v4 reference population PCA and are governed by the Indigenous data sovereignty principles of the Silent Genomes Project and the Indigenous Background Variant Library (IBVL).
