DELMICRON-a inter-lineage recombinant (IMAGE) Xia & He Publishing Inc. Caption Inter-lineage recombination occurs between AY.4 and BA.1, giving rise to Deltacron/Delmicron, where 4 common mutations are found in S-protein (T95I, G142D, T478K, D614G) and 1 common mutation is found in each ORF1a (T3255I) and ORF1b (P314F/P314L). This recombinant variant harbor spike protein from an Omicron BA.1 genome in a Delta AY.4 spine.
