The B.1.617 variant of SARS-CoV-2 carries two mutations, E484Q and L452R. The E484Q mutation is similar to E484K, a mutation found in the United Kingdom (lineage B.1.1.7) and South Africa (B.1.351) variants of the coronavirus. The L452R mutation has been found in fast spreading variants in California (B.1.427 and B.1.429).
