Another position of interest continues with Genetic Acquisition activity into Taiwan. 286E is found on A/Taiwan/126 and one US specimen, NY3629, a total of 2 PF11 instances. No point of Ultimate Origin is yet established at this time for 286E; however, instability exists at this amino acid position throughout the H1N1 and H5N1 serotypes. At least 6 values are on file at 286 within our reservoirs of interest (Donor Candidate serotypes).
286K: PF11 Consensus
286E: Taiwan126, NY3629
286H: 1918 (3), IowaSwine1930
286L: Lab_Virulent_hvPR8_34
286M: H5N1 Viet human (2) and Hunan Chicken
286Q: Seasonal H1N1 2008, 2009, WSN33 and KoreaSwineS175
Continued H1 (Hemagglutinin) high variability is expected due to 286 instability and geographic spread of 200T and 414I.
