Final answer:
Yes, there are several known lineages of SARS-CoV-2 with insertions in their genomes, such as Mu, B.1.1.28, and B.1.
Step-by-step explanation:
There are several known lineages of SARS-CoV-2 with insertions in their genomes. However, these insertions may not be visible in tools based on GISAID sequences. One example is the Mu lineage, which has an insertion at S:YY144-145TSN. Another example is the B.1.1.28 lineage, which has an insertion at S:ins214ANRN. Additionally, the B.1 lineage has an insertion at S:ins214QAS, which is now assigned the lineage B.1.639. These insertions have been observed in lineages occurring in the wild, while there may be more insertions in lab experiments.
