Association of RANBP1 haplotype with smooth pursuit eye movement abnormality
ReviewHyun Sub Cheong et al.(2011)· American Journal of Medical Genetics Part B: Neuropsychiatric Genetics

This comprehensive review examines the genomics of schizophrenia and pharmacogenomics of antipsychotic drugs, synthesizing evidence on over 200 genes associated with psychotic disorders. The authors discuss five categories of genes relevant to antipsychotic response: disease-associated genes, mechanism-of-action genes, drug metabolism genes (particularly CYP2D6, CYP2C19, CYP2C9, CYP3A4), drug transporter genes, and pleiotropic genes. The review details pharmacogenomic profiles of 20+ antipsychotic drugs and demonstrates significant ethnic and interindividual variation in drug metabolism phenotypes, with examples including CYP2D6 extensive metabolizers (55.71% of population), intermediate metabolizers (34.7%), poor metabolizers (2.28%), and ultra-rapid metabolizers (7.31%).

Influence of NOS1 on Verbal Intelligence and Working Memory in Both Patients With Schizophrenia and Healthy Control Subjects
ReviewGary Donohoe et al.(2009)· Archives of General Psychiatry

This comprehensive review synthesizes genomic and pharmacogenomic research in schizophrenia, discussing over 200 candidate genes associated with psychotic disorders, genetic mechanisms including copy number variants and microRNA alterations, and pharmacogenomic factors affecting antipsychotic efficacy and safety. Key genes covered include dopamine receptors (DRD1-5), dysbindin (DTNBP1), DISC1, neurotrophic factors, and metabolic enzymes such as CYP2D6, CYP3A4, and COMT, with emphasis on genotype-phenotype correlations in antipsychotic response and side effects.

About CTLA4

This gene is a member of the immunoglobulin superfamily and encodes a protein which transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases.
