Research Progress on Pathogenic Genes of Ph-like Acute Lymphoblastic Leukemia--Review

Abstract

Abstract Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL or BCR-ABL1-like ALL) is a kind of acute leukemia which has the similar gene expression profiles and manifests the biological behavior same to Ph-positive ALL, but lacks the BCR-ABL1 fusion gene. Ph-like ALL was involved in multiple abnormal changes of genomes, activating kinase and cytokine receptor signaling. This review focuses on the progress of classical genetic abnormalities of PH-like ALL in the JAK-STAT signaling, ABL kinase activation, TKI resistance in Ph-like ALL, SH2B3 gene inactivating mutation and IKZF1 gene abnormality. Besides, also summarizes the frontier progress of novel gene mutation (ATF7IP exon 9 fused with PDGFRB exon 11, PDGFRBC843G mutation caused by fusion of exon 11-23 of PDGFRB with exon 1-6 of AGGF1 gene) in recent years.
