INSACOG. INSACOG is a consortium of government panel involved in genome sequencing of Covid-19. INSACOG also said that AY.3 has been identified as a new sub-lineage of Delta and it is defined by 'ORF1a:I3731V common AY.1 mutations except for S:417'.
It is primarily seen in America with a single reclassified case in the UK and India. There are no known significant properties of this mutation but since it is a Delta VOC sub-lineage, INSACOG will continue to monitor it, a recent bulletin stated. "It is likely that neither AY.1 nor AY.2 is more transmissible than Delta.
They also continue to be below 1% in available sequences from June in India," the INSACOG said. INSACOG is also tracking the status and spread of Delta plus variant of
