Protein tyrosine phosphatase non-receptor type 2 (PTPN2) gene polymorphisms (rs2542151, rs7234029) in Egyptian Behçet's disease patients: a preliminary report.

Single nucleotide polymorphisms (SNPs) of the protein tyrosine phosphatase non-receptor type 2 (PTPN2) gene have been documented to be linked with several autoimmune disorders including Behçet's disease (BD). PTPN2 SNPs rs2542151 and rs7234029 have been assessed using real-time PCR in 96 BD patients and 50 controls matched by age and gender. Patients were categorized into groups according to the disease phenotypes and severity.

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.
