▶CTLA-4 polymorphisms are associated with treatment outcomes of patients with multiple myeloma receiving bortezomib-based regimensAssociationN=240Xiao-Ying Qin et al.(2018)· Annals of Hematology
This study investigated five CTLA-4 SNPs (rs733618, rs4553808, rs5742909, rs3087243, rs231775) in 86 multiple myeloma patients and 154 controls to evaluate their association with bortezomib treatment outcomes. The rs733618 GG genotype was associated with significantly lower disease-free survival (0% vs 57.4%, P=0.020) and overall survival (46.3% vs 83.3%, P=0.026) compared to GA+AA carriers, with multivariate analysis showing rs733618 GG as a risk factor for overall survival (HR=0.012, 95% CI=0.001-0.199, P=0.002).
▶Association of RANBP1 haplotype with smooth pursuit eye movement abnormalityReviewHyun 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%).
▶Polymorphisms in the CD28/CTLA4/ICOS genes: role in malignant melanoma susceptibility and prognosis?AssociationN=1,497Marna G. Bouwhuis et al.(2010)· Cancer Immunology, Immunotherapy
This case-control study examined 28 SNPs across CD28, CTLA4, and ICOS genes in 763 German melanoma patients and 734 controls to assess association with melanoma susceptibility and prognosis. While two CD28 polymorphisms (rs3181098 and rs3181100) showed differential allele distribution (OR 1.18, P=0.05 and OR 0.83, P=0.02 respectively), after multiple testing correction no convincing associations with melanoma risk or disease prognosis were detected.
▶Lack of association of functional CTLA4 polymorphisms with juvenile idiopathic arthritisAssociationN=1,447Sampath Prahalad et al.(2008)· Arthritis & Rheumatism
This study investigated the association between three functional CTLA4 polymorphisms (C-318T rs5742909, A49G rs231775, and CT60 rs3087243) and juvenile idiopathic arthritis (JIA) using family-based and case-control analyses in a large cohort (531 JIA families plus 365 independent JIA cases and 551 controls). The authors found no significant associations between any of the CTLA4 variants and JIA overall or most JIA subtypes, and a meta-analysis of published studies also failed to confirm an association between CTLA4 variants and JIA.
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.
