B-cell depleting therapies may lead to prolonged disease and viral shedding in individuals infected with SARS-CoV-2 and this viral persistence raises concern for viral evolution. We report on the sequencing of early and late samples from a 335-day infection in an immunocompromised patient. The virus accumulated a unique deletion in the amino-terminal domain of the spike protein, and complete deletion of ORF7b and ORF8, the first report of its kind in an immunocompromised patient. Overall, the unique viral mutations found in this study
