5Result: Chromatographic DNA sequencing data of the four patients exhibited valine 524 codon ""GTT"" (reference sequence) that was substituted by aspartic acid 524 codon ""GAT"" (V524D)."
Figure: (A) The align of Korean COVID-19 and wild ype SARS-CoV2 spike gene amino acid sequence revealed three new mutations (G504D/V524D/P579L) highlighted by green with red letter.
Figure: The representative chromatography of D614G (A), G504D (B), V524D (C), and P579L (D) mutation was shown from the DNA sequencing results of four Korean COVID-19 patients.
