I was reading an article with title "characterizing sars cov 2 mutations in the united states" lately and got confused about SNP (single nucleotide polymorphism). On page 3 of this article, it mentioned that 4968 mutations are identified in 7823 strains. Then, it talks about "in this work, we extract 7823 single nucleotide polymorphism (SNP) profiles from genome isolates collected in the united states." So, why is it 7823 SNPs ? I thought that, more than likely, it should be 4968. Any comments are greatly appreciated.
