Create visualization of binding affinities between SARS-CoV-2 S variants and ACE2 variants across diverse human populations.
The interaction between SARS-CoV-2 Spike (S) and human angiotensin-converting enzyme 2 (ACE2) enables viral entry. Missense mutations in S or ACE2 can increase the binding affinity which may increase susceptibility to infection in different populations. Missense variants in ACE2 are rare but distributed unevenly across populations.
- Filter SARS-CoV-2 VCFs for samples derived from metagenomic sampling with geolocation metadata
- Identify nonsynonymous SNPs in S protein (from SARS-CoV-2 VCFs) and nonsynonymous SNPs in the ACE2 receptor (from 1kGP project VCFs)
- Calculate predicted binding affinity for combinations of S variants and ACE2 variants
- Visualize S protein variants geographically with binding affinity data
- 5,521,380 samples with country-level location\
- 7,638 unique variants
