All Fatal Ukraine Cases at GISAID Have RBD D225G. -- (Recombinomics)
These are the same four samples that have D225G (see list below). This association suggests that swine H1N1 with D225G is more aggressive and is cause for concern............It was the jumping of D225G that allowed for prediction of the marker in Ukraine prior to release of the sequences by Mill Hill. This type of jumping has been described in detail for H5N1 and seasonal H1N1 . This type of jumping via recombination and identification of markers that make frequent jumps are the underlying concepts that allow for the D225G.....prediction.
