Is V600E the only mutation that can be detected with the codon 600 assay in the BRAF Pyro Kit?

No, the V600E is not the only mutation that can be detected with the BRAF Pyro Kit.  The sequence to analyze can be changed post-run to allow detection also of V600M (GTG>ATG), V600A (GTG>GCG) and V600G (GTG>GGG).
