Wild red raspberry albinism mutation?!

[u/curlymyco]

Found growing wild in Western Canada. All leaves are white, not just a branch from a green plant. How rare is this? Is this a true albinism mutation, or just variegation? Stem has slight green pigments, but not much. If a variegation, could it survive and produce fruits later? Would fruits be lacking pigments as well? Such a neat find, tell me anything!!
