N501Y...has been found in other countries, including the United Kingdom
Our clinicians have also warned us that things have changed and that younger, previously healthy people are now becoming very sick.
I should note here that there’s another strain in South Africa that is bringing on similar concerns. This one has eight mutations in the Spike protein, with three of them (K417N, E484K and N501Y) that may have some functional role.
The South African variant ‘501.V2’ is characterised by N501Y, E484K and K417N mutations in the S protein – so it shares the N501Y mutation with the UK variant, but the other two mutations are not found in the UK variant. Similarly, the South African variant does not contain the 69-70del mutation that is found in the UK variant.
