— RGS16 RGS16 H137R
Missense variant in RGS16 that substitutes histidine for arginine at position 137 of the G-protein signaling regulator expressed in the suprachiasmatic nucleus; the common C allele (Arg137, ~97.5% globally) has modestly reduced RGS16 function compared to the rare T allele (His137, ~2.5%), which is associated with morningness through enhanced cAMP gating in the master circadian clock
