Here's my take on the protein sequences encoded by the alleles reported at #geneeditsummit for #CRISPRbabies. Lulu's mutation (delta15) leads to a five amino acid deletion, but the protein largely resembles wild type. The consequence of this mutation is unknown... (1) Thread Nana has two different mutations (excluding possible mosaicity). The first (ins1) leads to a variant that is similar to the well-studied delta 32 variant, except it has an additional 11 amino acids that are neither in WT or delta 32... (2) Thread
