Convergence of heavy or light chains in antibodies recognising pathogens could drive mutations in these pathogens. Here the authors examine antibodies against SARS-CoV-2 and find that a conserved VL6-57 light chain recognising a conserved motif in the spike protein is associated with virus mutations and could drive changes in SARS-CoV-2 omicron variants.
