All four of the earlier released sequences that had no clinical outcomes at initial release are noted as fatal on this chart if we are reading correctly.
The four cases are each genetically divergent.
Three share the common 377K. No individual change appears on all four fatal sequences. In fact, no two of the four share any other polymorphism than the three sharing 377K.
3 out of 4 were fatal. They were early and representative. Now S188T is dominant.
All four are on the Ellis Figure3 [1] chart
marked as fatality and all four were updated yesterday on GISAID as "
Deceased". Two were recent and all four are
divergent.
GISAID 2010-12-20 deposited sequences are notated with green boxes on the Ellis Figure3 [1] chart.

GeneWurx_UK_December_Emerging_Genetics_v3.xlsHyper-Zoonotic Polymorphism DetailsPlease excuse the intermediate markings on these sequences. The following are rough lab notes, but divergence may be ascertained easily.
The common ground among these sequences and those in the database on either side of them temporally, especially Iran, is the
high quantity of polymorphisms that are
novel or rare to
pH1N1 and that also appear in zoonotic reservoirs, particularly
H3N8, H5N1 and H7N7.
Even small genetic adjustments from animal vectors into human infections, especially
H3N8, may create
variant behaviour. This potential era of
zoonotic sub-segment spillover merits as much investigation for severity (in combination) as does the recognised
225G.
