PAWR (pro-apoptotic WT1 regulator) is a pro-apoptotic gene that was among the top differentially expressed genes in peripheral blood mononuclear cells (PBMCs) from multiple sclerosis (MS) patients and might be involved in the regulation of MS (Comabella et al., 2016; Ghoveud et al., 2020). Here, WT1 is linked to myeloid sarcoma.
