Columbia-studie: Genredigering i embryo er effektiv, men for risikabel for klinisk bruk

17 kilder
  • Et team fra Columbia University publiserte onsdag en studie i Nature som viser at base-redigering kan endre gener i menneskelige embryoer presist, men at det fører til farlige bivirkninger.
  • Base-redigering oppnådde 100 prosent nøyaktighet i enkelte tilfeller, men utløste også kromosomslettinger, utilsiktede endringer og mosaikkmønstre som gjør resultatene uforutsigbare.
  • Hovedforsker Dieter Egli sier funnene bør motvirke for tidlig klinisk bruk, samtidig som de øker forståelsen av DNA-reparasjon i tidlige embryoer.
