When I read this asthma.org.uk blogpost, I thought of those friends in public life with asthma which standard treatments could not alleviate and who have died in recent years. The newly NICE-approved Dupilumab, which appears to have a gene-suppressing effect, might have saved them. Gene silencing is a "hot" line of research at present and has already produced a couple of treatments for congenital diseases, with promise of much more to come. It should be stressed that these treatments are different from gene editing in that they do not alter a person's physical legacy and can be unwound. There is more on Radio 4's Inside Health.
