Mainly asking you for my own data, but I certainly think so (given how easy/cheap it is now). My son was non-verbal till he was 3 and as we later discovered, mutated on both 1298/677 due to bad genes from both my ex-wife and I. When we gave him an injection of methyl-b12 (the primary course of supplementation for these mutations), he literally started talking the next day. I've heard this story so. many. times. in the autistic community. So at this point I always ask people about it.
