ADRA1A and myeloid sarcoma: Although there is evidence for the association of SZ with some MS associated genes like methylenetetrahydrofolate reductase (MTHFR) (Ellingrod et al., 2008) and alpha-1A adrenergic receptor (ADRA1A) (Cheng et al., 2012), none of these associations have led to a common metabolic pathway, which actually links MS with SZ providing the rationale for research toward a “drugable” therapeutic/prophylactic target.
