IL2RA and myeloid sarcoma: Actually, MS can be associated with severely susceptibility loci, including chromosome 6p21 (three serological alleles of the HLA, encoded in the major histocompatibility complex), 10p15.1 [encoding the interleukin‐2 receptor (IL‐2RA)] and 5p13.2 [encoding the interleukin‐7 receptor (IL‐7RA)]30, as well as 12p13.31 [encoding the C-type lectin-like 1 (CLECL1)] 17q21.32 [encoding the EF-hand calcium-binding domain 13 (EFCAB13)]31,32.
