In addition, at the biological function level, in June 2020, researchers from Turkey identified a unique expression profile of FAM83A in their established metabolic and protein–protein interaction networks of SARS-CoV-2-infected epithelial cells (Karakurt and Pınar, 2020), implying the specific role of FAM83A in distinguishing upper airway samples with SARS-CoV-2 infection from those of disease controls or with other infections. This evidence concerns the gene SACK1A and infection.
