Known amino acid sequence-changing variants of human OX2 receptor. The variants are OX210 Pro/Ser, OX211 Pro/Thr, OX2193 Cys/Ser, OX2293 Ile/Val, OX2308 Val/Ile, and OX2401 Thr/Ile. The findings originate from Peyron et al. (2000) and Olafsdottir et al. (2001). The figure is modified from Kukkonen, J. P. (2013).
