JIA and IBD are characterized by divergent peripheral blood transcriptomes, the genetic regulation of which displays limited disease specificity, implying that disease-specific genetic influences are largely independent of, or downstream of, eQTL effects.
High levels of TRAP5b, NTX-I and collagen II in JIA in contrast to more pronounced aggrecan and COMP degradation in juvenile knee injuries, suggests that JIA patients have a unique biomarker pattern, different from healthy and knee-injured children.

The patient had received successive tumor necrosis factor (TNF) antagonists and abatacept to treat juvenile idiopathic arthritis, with negative results for polymerase chain reaction and acid-fast bacilli on smear, had normal cerebrospinal fluid (CSF) adenosine deaminase and glucose levels.

Five SNPs within the genes AFF3, IL2/IL21, IL7R, CTLA4 and CD226, previously associated with multiple autoimmune diseases were genotyped, in a large data set of Caucasian JIA patients and controls, and tested for association with JIA.

A lower median AMH levels [2.65(0.47-9.08) vs. 4.83(0.74-17.24) ng/mL, p = .029] with a higher LH [8.44 ± 4.14 vs. 6.03 ± 2.80 IU/L, p = .014] and estradiol levels [52.3(25.8-227.4) vs. 38.9(26.2-133.6) pg/mL, p = .008] were observed in JIA compared to control group.
SNPs in or near PTPN22, VTCN1, the IL2-IL21 region, ANKRD55 and TNFA were confirmed to be associated with JIA (p<0.05), strengthening the evidence for involvement of these genes in JIA.

Variants originally associated with juvenile idiopathic arthritis (VTCN1 gene), sarcoidosis (ANXA11 gene), primary biliary cirrhosis (IL12RB2 gene) and celiac disease (LPP gene) were not associated with type 1 diabetes in our dataset.
