Mutations

What we know about California COVID variant B.1.427/ B.1.429 Researchers from the University of California, San Francisco, say it should be listed as a "variant of concern." Newsweek

A new coronavirus variant that was first identified in California is now taking hold in some parts of the state—but what do we currently know about it?

The variant actually comes in two forms, known as B.1.427 and B.1.429, both of which carry a similar, albeit slightly differing, set of genetic mutations—including three that affect the spike protein of the SARS-CoV-2 virus.

A new study identifies seven U.S. virus variants with the same worrying mutation.

As Americans anxiously watch the spread of coronavirus variants that were first identified in Britain and South Africa, scientists are finding a number of new variants that seem to have originated in the United States — and many of them may pose the same kind of extra-contagious threat.

In a study posted on Sunday, a team of researchers reported seven growing lineages of the coronavirus, spotted in states across the country. All have gained a mutation at the exact same spot in their genes.

UK’s Kent virus variant becoming more resistant, scientists warn Sequencing of coronavirus samples must be reduced from five days to 36 hours to help fight against outbreaks. POLITICO

LONDON — The dominant coronavirus variant in the U.K. is becoming more resistant to vaccines, scientific experts have warned.

Two leading scientists in the U.K. warned Wednesday that the variant of the virus first identified in Kent has acquired the same E484K mutation on its spike protein that makes the South Africa variant so worrying for experts.
