Gene Expression and Pathophysiology Comments
P2RY8 is reported to have oncogenic potential [6,9]. P2RY8-CRLF2 gene fusion, which results from PAR1 deletion of Xp22.3 and Yp11.3, is found to be associated with B-progenitor acute lymphoblastic leukemia (ALL) and ALL associated with Down syndrome [4,7-8,11]. Acute lymphoblastic leukemias in children with Down syndrome is associated with recurrent deletion of P2RY8 gene, which causes CRLR2 gene deregulation [5,10]. Somatic mutations in P2RY8 gene are identified in patients with diffuse large B-cell lymphoma (DLBCL) [9]. Increased expression of P2RY8 is found to be associated with leukemia [6]. A promoter swapping event juxtaposing SOX5 coding region to the P2RY8 promoter, which lead to the formation of a novel fusion gene involving P2RY8 and SOX5, is found to be associated with primary splenic follicular lymphoma (PSFL)[12] (Based on a single PSFL case).
