▶Polymorphism in alpha 2A adrenergic receptor gene is associated with sialorrhea in schizophrenia patients on clozapine treatmentAssociationN=237Anssi Solismaa et al.(2014)· Human Psychopharmacology: Clinical and Experimental
This dissertation examined pharmacogenetic associations with clozapine adverse effects in 237 Finnish schizophrenia patients. ADRA2A rs1800544 was associated with clozapine-induced sialorrhea (OR 2.13, 95% CI: 1.17-3.88, p=0.013). Eight HNMT SNPs in complete linkage disequilibrium (r²=1) were associated with sedation. CHRM3 rs685548 and weighted genetic risk scores from HTR4, HTR7, TPH1, CHRM2, ABCB1, and OPRM1 were associated with anticholinergic symptoms.
About CHRM3
The muscarinic cholinergic receptors belong to a larger family of G protein-coupled receptors. The functional diversity of these receptors is defined by the binding of acetylcholine and includes cellular responses such as adenylate cyclase inhibition, phosphoinositide degeneration, and potassium channel mediation. Muscarinic receptors influence many effects of acetylcholine in the central and peripheral nervous system. The muscarinic cholinergic receptor 3 controls smooth muscle contraction and its stimulation causes secretion of glandular tissue. Alternative promoter use and alternative splicing results in multiple transcript variants that have different tissue specificities. [provided by RefSeq, Dec 2016]
