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]: :

  1. Insertion of the EPOR locus distal to the immunoglobulin heavy chain (IGH) locus enhancer
  2. Insertion of EPOR into the immunoglobulin kappa chain (IGK)
  3. Reciprocal t(14;19)(q32;p13) rearrangement of IGH to EPOR
  4. 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.
