This tracker doesn't include a suspected BA.4 sequence from #Maryland

Reason: #Amplicon #Dropout in the key region containing signature spike aa 452/486 which partly defines this lineage.

To BA.4 or not to... that is the real question!

BA.4 signature -

From PANGO issue #517 (#silcn): N:P151S, L452R, F486V (@CorneliusRoemer's query BA.2* + 12160A, 9866., 27788T)

From @Tuliodna - N:P151S, NS7b: L11F, NSP1 141-143del

There is overlap but missing many.. Image
