Transmembrane Protein 187 (TMEM187) and Interleukin 1 Receptor Associated Kinase (IRAK1) gene polymorphism association with rheumatoid arthritis susceptibility in Egyptian patients.

Rheumatoid arthritis (RA) is a chronic auto-inflammatory disease of connective tissue with progressive joint damage and systemic disorders. RA is considered a multifactorial disease triggered by a genetic predisposition and environmental factors. Polymorphisms have been identified in the Xq28 locus as risk loci for RA.

Systemic lupus erythematosus: genetic variants in Xq28 region.

Objectives: Methyl-CpG-binding protein 2 (MECP2) and interleukin-1 receptor-associated kinase (IRAK1) are encoded by adjacent X-linked genes and recognized for their role in regulation of inflammation. The present case control study was conducted to detect the genetic association between MECP2 (rs1734791) and IRAK1 (rs1059703) single nucleotide polymorphisms (SNPs) and susceptibility to systemic lupus erythematosus (SLE), and the possible association of these SNPs and severity of SLE.

Material And Methods: Fifty patients with SLE and 100 healthy controls were included in this study.
