Genes
Most Studied Genes in Gene Editing
The genes that editing programmes actually aim at, and why each was chosen.
كيف تُبنى هذه القائمة
Editing programmes cluster around a small number of genes, and the reasons are consistent: the gene is in the liver where delivery works, or switching it off is known to be safe because people are born without it, or the disease is caused by too much of something rather than too little.
