Probably specific to the Ph-like subgroup of B-ALL
Iacobucci et al. (2016) identified four types of EPOR rearrangement[1]: :
- Insertion of the EPOR locus distal to the immunoglobulin heavy chain (IGH) locus enhancer
- Insertion of EPOR into the immunoglobulin kappa chain (IGK)
- Reciprocal t(14;19)(q32;p13) rearrangement of IGH to EPOR
- Intrachromosomal inversion of chromosome 19 that juxtaposes
EPOR to the up-stream region ofLAIR1 (leukocyte-associated immunoglobulin- like receptor 1) at chromosome 19q13
