A significant negative value indicates that polymorphic sites are under purifying selection. A significant positive value indicates that polymorphic sites are under balancing selection. The abbreviations in the genetic schematic represent individual domains as follows. 5’UTR = 5’ untranslated region, B1 = 1st BIR domain, S1 = 1st serine rich domain, B2 = 2nd BIR domain, S2 = 2nd serine rich domain, Z = Zing ring finger motif, and U = 3’ untranslated region. The coding region begins at nucleotide 0 and ends at nucleotide 1,212.
