Many thanks to Prof Yoshihiro Kawaoka and Dr Eileen Maher who answered my email and pointed me to a massive list of the known genetic changes that determine influenza virus phenotypic characteristics of importance, in a downloadable PDF format, on the Center for Disease Control and Prevention's (CDC) website.

So I will add a fey more"key" mutations to my draft and place it on my dedicated influenza page (http://www.uq.edu.au/vdu/VDUInfluenza.htm) but I think the CDC have it all very well covered - so I no longer need to curate my own list until the day I die!
Also check out Dr Amesh A .Adalja's paper containing a Table of mutations and thanks to Robyn Hall for some additional info.
