IL2 and myeloid sarcoma: Apart from transcripts involved in IL-2 signalling such as CISH, increased expression of transcripts associated with protein synthesis and proliferation (EEF1A1, EEF1B2, EIF3L, PIK3IP1 and TPT1) was found in twins with MS compared with unaffected twins (Extended Data Fig. 5f, g, Supplementary Table 5).
