hey i just saw your rb of the jiankui he tweet and he didnāt actually manage to make the twins immune to hiv - the mutation is a 32bp deletion and you have to have it in both copies of the gene for it to confer immunity (but thereās evidence that itās not 100%) and his results were a 15bp deletion in one copy for one of the twins and a 4bp deletion in both copies for the other, so not the mutation that confers HIV immunity. itās unclear what effect these mutations would have, if any. just wanted to clarify bc iām a biologist haha
Aw man
