There is one clinical trial.
This study aims: 1. To investigate the association between single nucleotide polymorphisms of PTPN22 gene (rs2476601, rs33996649 and rs2488457) and inflammatory bowel disease. 2. To correlate the relation between the studied SNPs and disease activity /response to therapy.
There are 24 exons in the gene (NCBI website).About 21 SNPs were found in PTPN22 gene (rs1310182, rs3789604, rs33996649, rs1217414, rs2476601, rs12760457, rs2488457,,,,etc).SNP rs2476601 (C1858>T) in exon 14 results in the substitution of arginine 620 with a tryptophan residue in the protein product (referred to as 620W variant) (Spalinger et al., 2016).
Description: Three single nucleotide polymorphisms in the lymphoid tyrosine phosphatase gene(SNP (G788>A) in exon10, SNP (C1858>T) in exon 14 and SNP (G -1123>C) in the promoter region ) will be assessed in 100 patients diagnosed as inflammatory bowel disease and 100 healthy subjects by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) to detect association between these polymorphisms and inflammatory bowel diseaseMeasure: Association between single nucleotide polymorphisms of Lymphoid Tyrosine Phosphatase gene (rs2476601, rs33996649 and rs2488457) and inflammatory bowel disease Time: baseline
Description: Serum Erythrocyte Sedimentation Rate ,C-Reactive Protien ,Anti Nuclear Antibody ,Antineutrophil Cytoplasmic Antibody (ANCA) and Anti Saccharomyces Cerevisiae (ASCA) and fecal calprotectin will be done to all patients.The three investigated polymorphisms in LYP will be correlated with the markers of disease activity and IBD patients response to therapy.Measure: To correlate the relation between the studied SNPs and disease activity /response to therapy. Time: baseline
