Abstract:
The Streptococcus pneumoniae capsule is essential for disease pathogenesis, suggesting that even minor genetic changes within the cps locus could potentially have important consequences. Arends et al. (D. W. Arends, W. R. Miellet, J. D. Langereis, T. H. A. Ederveen, et al., Infect Immun 89:e00246-21, 2021, https://doi.org/10.1128/IAI.00246-21) have identified 79 different nonsynonymous single-nucleotide polymorphisms (SNPs) in the cps locus of 338 19A serotype strains and shown significant variations between strains in nucleotide sugar content and capsule shedding. Further work is required to characterize whether any of these changes have important functional consequences on capsule-host interactions.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
