This is a shortened version of the article that appeared in STAT:HEALTHWhat the surprising mutations in the monkeypox virus could indicate about the new outbreak By Andrew Joseph June 2, 2022 Picture above is a colorized transmission electron micrograph of monkeypox virus particles (teal) cultivated and purified from cell culture.NIAID When scientists investigate the spread of an infectious disease, one area they look at is the genetic sequences of the pathogen. But there’s a snag when it comes to the monkeypox virus (a virus that has one positive sense DNA strand and one negative antisense DNA strand), which is now causing an unprecedented outbreak of several hundred infections in some 30 countries where it’s not typically seen. But as researchers around the world share monkeypox genetic sequences from the current outbreak, the genomes have revealed something odd: There are way more mutations than expected. So many mutations in such a short amount of time might seem worrisome, if, perhaps, it meant the virus was evolving to spread more efficiently among people. But scientists have a different hypothesis (still a hypothesis, they stress, one that needs to be further studied) about what these mutations say about these infections — and, in turn, what that can illuminate about this outbreak. Below, STAT explores some questions the sequences have raised, with insights from Richard Neher, a computational evolutionary biologist at the University of Basel. What do these sequences show in terms of mutations? Most notably, there are a whole lot of mutations that appear across the new sequences. The genomes from the current outbreak share 40-some mutations with each other that distinguish them from their closest relatives, which were from around 2018. (The exact number of mutations varies depending on how certain changes are counted.) Based on normal evolutionary timelines, scientists would expect a virus like monkeypox to pick up that many mutations over perhaps 50 years, not four, Neher said. “That is somewhat remarkable,” he said. Why are there so many mutations? A lot of mutations could be bad — perhaps the virus has changed so much because it’s grown more fit and gotten better at transmitting among people. Monkeypox, unlike something like SARS-2, has historically not been considered to be a particularly efficient person-to-person spreader. But there could be another explanation. We tend to think of mutations as the result of haphazard mistakes that occur as genetic material is copied. Some mutations don’t have any real effect on the virus, some can actually be harmful, and some can give it an advantage over other strains. But changes to viral genomes happen as a result of other mechanisms as well — and there are clues this is what’s happening with these monkeypox sequences. The majority of the changes, for example, are specific swaps in the “letters” that make up DNA — namely G to A or C to T. Not only that, but those mutations are happening at particular locations within sequences. “These aren’t just sort of random collections of mutations,” Neher said. “These are mutations of a very specific type.” Here’s what might be happening: Some hosts (in this case, that’s people) have, as part of their immune systems, enzymes that are designed to induce mutations in whatever viruses they encounter. The idea behind such a sabotage scheme is that if you trigger enough mutations, certainly some of them will kill the virus. The virus won’t be able to replicate, and what will be left “is just a dead piece of DNA,” Neher said. It’d be like rearranging the letters on your enemy’s typewriter so they can’t get a clear message out. The strategy is not always foolproof, and some viruses might not pick up enough harmful mutations to be stopped. These survivors will, however, carry evidence of the genetic onslaught they encountered in the form of certain mutations, perhaps those that weren’t all that harmful or were neutral. The mutations might appear repeatedly, just like the ones in these monkeypox sequences. Scientists have likened these mutations to scars leftover from past fights with the host. The enzyme vs. virus battles could also explain why the virus picked up so many mutations so fast. The mutations are not from the typical copying mistakes the virus made as it replicated. They’re battle wounds from when the host tried to fight the virus off. Question: Did you read the article above?
