Expert reaction to South African variant of SARS-CoV-2, as mentioned by Matt Hancock at the Downing Street press briefing. Science Media Centre, 23. Dezember 2020, abgerufen am 24. Dezember 2020 (englisch): „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.“
