I membri della Camera bassa britannica hanno approvato martedì (per 328 voti a favore e 128 contrari) un progetto di legge che vuole autorizzare una tecnica di fecondazione in vitro che apre le porte alla concezione di bambini con il DNA di tre persone: un padre, una madre e un terzo "genitore" di sesso femminile.
Questo metodo, ancora in fase sperimentale, è stato studiato per aiutare le famiglie toccate dalla miopatia mitocondriale, una condizione incurabile che si trasmette geneticamente per linea materna. I sintomi sono distrofia muscolare, insufficienza cardiaca, epatica e renale.
Se il testo verrà approvato anche dalla Camera alta, il Regno Unito sarà il primo paese ad autorizzare la modifica genetica degli embrioni, che la legge attualmente proibisce. I contrari al testo temono che queste tecniche possano condurre alla creazione di "bambini su misura".
