This mutated gene copy was also duplicated in the cancer genome, resulting in elevated expression.
One result stood out in the DNA of the people who were less at risk for malaria: Two genes that provide instructions for two proteins called glycophorin A and glycophorin B were snipped, fused together and duplicated.
Twin genes or duplicated regulatory regions result, and although one in the pair usually has to keep doing its original job, the other is free to mutate and take on new roles that can enhance an organism's survival.
As the authors note, «the presence of duplicated and diverged genomic regions probably promotes functional novelty between resulting gene copies, following positive selection.»
More recently, however, it has become appreciated that after gene duplication, the resulting duplicates are often «subfunctionalized» and accumulate complementary mutations: the two genes together perform the function formerly carried out by a single ancestral gene.
