The isolated SNVs and genomic rearrangements, reflect the intra-patient capacity of the polymorphic quasispecies, which may arise rapidly during the outbreak, allowing immunological escape of the virus, offering resistance to anti-viral drugs and affecting the sensitivity of the molecular diagnostics assays. Here, we explore intra-host genomic variants and low-frequency polymorphic quasispecies in Next Generation Sequencing (NGS) data derived from patients infected by SARS-CoV-2. The S1 subunit consists of a signal peptide and the NT and receptor binding (RB) domains, with the latter sharing only 40% amino acid identity with other SARS-related CoVs. Our analysis revealed that similarly to other genomic regions, the S1 subunit hosts many low-frequency SNVs, characterized by higher density compared to the rest of the S gene sequence (Figure 1-E) . ./cache/cord-268339-jxm69ndw.txt ./txt/cord-268339-jxm69ndw.txt
