"We think this finding may be a clue to the specific disease pathway that leads to arthritis," said Behrens, a pediatric rheumatologist at Children's Hospital. "We currently use medicines called tumor necrosis factor blockers to treat children with JIA. However, not all children respond to these drugs, and other children may develop severe allergic reactions and other side effects. If we can fully identify all the genes that interact with environmental risk factors, we might develop more targeted treatments with fewer side effects."
"The high-resolution genome-wide association approach has very markedly enhanced our ability to identify disease genes in complex disorders such as JIA, and what is remarkable about this discovery is that it appears there may be a common genetic factor predisposing to all seven forms of the disease," said Dr. Hakonarson.
The study was supported by an Institutional Research Development Award from Children's Hospital and development research awards from the Cotswold Foundation, the Nickolett Fund, and the Arthritis Foundation of Eastern Pennsylvania.
