The mutation S:Q628K on top of BA.1 is rather interesting. It's appeared homoplasically in the US and the UK, in both cases showing a clear growth advantage over BA.1.

This is a proposal for the US lineage with S:Q628K. The mutation appeared on top of the BA.1.15 sublineage.

The growth advantage is very clear and sustained.
