Referral: Virology Blog On D225G Mutation
There has been a lot of speculation regarding the D225G mutation first announced in Norway last November, suggesting that it may increase the virulence of the novel H1N1 virus.
This mutation, sometimes called D222G (or D225G in influenza H3 numbering) had actually been detected months earlier, and in many other countries. Norway was simply the first country to announce a possible connection between that mutation and greater virulence.
This mutation involves a single amino acid change in the HA1 gene at position 222 from aspartic acid (D) to glycine (G).
The World Health Organization's take on this mutation has been pretty consistent. It is worth following, and studying, but there is no evidence (as yet) that it poses a substantial public health hazard.
