Intronic Variants of the Angiotensin-Converting Enzyme 2 Gene Modulate Plasma ACE2 Levels and Possibly Confer Protection against Severe COVID-19

Figure 6

Lollipop plot showing the mean plasma ACE2 levels in individuals harboring specific ACE2 intronic variants and wild-type sequence at that particular locus. Red dots represent ACE2 levels in individual(s) harboring the specific variant, and green dots represent individuals harboring the reference sequence at that locus (three variants were identified in only one individual; therefore, the significance of the difference was not measured).
