Pharmacogenomic analysis of interferon receptor polymorphisms in multiple sclerosis

Genome-wide pharmacogenomic analysis of the response to interferon beta therapy in multiple sclerosis.

OBJECTIVE To identify promising candidate genes linked to interindividual differences in the efficacy of interferon beta therapy. Recombinant interferon beta therapy is widely used to reduce disease activity in multiple sclerosis (MS). However, up to 50% of patients continue to have relapses and worsening disability despite therapy. DESIGN We used a genome-wide pharmacogenomic approach to ide...

Molecular Analysis of rs2070744 and rs1799983 Polymorphisms of NOS3 Gene in Iranian Patients With Multiple Sclerosis

Introduction: Multiple Sclerosis (MS) is a disease of central nervous system that mainly causes lesions or plaques in the spinal cord and brain. The purpose of this study was to analyze the relation between c.-813C>T (rs2070744) and c.894G>T (rs1799983) polymorphisms of NOS3 gene and MS in Iranian patients. Methods: A total of 78 patients with MS and 80 healthy controls were screened for NOS3 ...

Pharmacogenomic study in patients with multiple sclerosis

Objectives:Weaimed to investigate the association between polymorphisms located in type I interferon (IFN)-induced genes, genes belonging to the toll-like receptor (TLR) pathway, and genes encoding neurotransmitter receptors and the response to IFN-b treatment in patients with multiple sclerosis (MS). Methods: In a first or screening phase of the study, 384 polymorphisms were genotyped in 830 p...

Association study of four polymorphisms in the interleukin-7 receptor alpha gene with multiple sclerosis in Eastern Iran

Objective(s): Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system (CNS) with unknown etiology. Various genetics and environmental factors contribute to the pathogenesis of the disease. The interleukin-7 receptor alpha chain (IL-7Ra) was identified as the first non-major histocompatibility complex (non-MHC) MS susceptibility locus. In this study we are tr...
