Scientists at Caltech and Columbia University, who have been scrutinising the genetic material of the virus to see how it is mutating, say the variant, known as B1526, first appeared in samples collected in November. The Caltech researchers discovered the rise in B1526 by scanning for mutations in hundreds of thousands of viral genetic sequences in a database called GISAID. The new variant accounts for 27 per cent of the viral sequences deposited. The researchers found two similar versions of the variant: one with the E484K mutation previously seen in the South African variant that is thought to partially diminish the immune response, and another with a mutation called S477N which may affect how tightly the virus binds to human cells. Both are grouped together as B1526. The E484K mutation was present in about 12 per cent of coronavirus samples that the researchers in Columbia sequenced from 1,142 patients from the university hospital. The study by Caltech was posted online on Tuesday, but the research by Columbia is not yet available in the public domain. Both studies, however, have not yet been peer-reviewed.
