Diseases
B-ALL; probably specific to the Phildelphia-like subgroup
Rearrangement Variants
Iacobucci et al. (2016) identified four types of EPOR rearrangement in the Phildelphia-like subgroup of B-ALL[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 of LAIR1 (leukocyte-associated immunoglobulin-like receptor 1) at chromosome 19q13
Co-occurring Lesions
EPOR rearrangements are frequently found in conjunction with IKZF1 deletions and PAX5 deletions within the Ph-like subgroup of ALL.
