My brother received his results from his BRAF testing out of USF – and it states "braf K – "the wild type". How can he be both K and the wild type. I thought K was a mutated gene – and wild is not mutated. Right now he is on yervoy – but needs to know his options – just in case yervoy fails.

Thanks very much-

  "V600E" means that in the BRAF protein, the normal (wild type) valine (V) at amino acid position 600 has been replaced with a glycine (E), which is a mutation. V600K means that the wild type valine at position 600 has been replaced with a lysine (K), which is also a mutation. BRAF V600E and V600K both respond to Zelboraf. I suggest that you ask your doctor to clarify what is going on here.
