From the facts that; primary ITP provocation is a result of immune system gene dysregulation, lncRNAs are immune gene regulatory molecules, IFNG-AS1 and GAS5 are two lncRNAs that are directly linked to autoimmune disorders, previously related to adult ITP and no other previous study tested the expression of these genes in childhood ITP, we construct this case-control study to elucidate expressions of target lncRNAs in childhood ITP and their association with pathophysiology and clinical features of the disease as well as their association with types and treatment. The gene discussed is IFNG; the disease is autoimmune thrombocytopenic purpura.
