No significant differences were found comparing the IFN-γ level between patients with MS and patient without MS in response to the ancestral (MS median 5.11 pg/ml, IQR: 0.87–19.9; no MS median 3.89 pg/ml, IQR: 1–79; P = 0.62) or to Delta peptide pool (MS median 6.1 pg/ml, IQR: 0.82–14.9; no MS median 4.56 pg/ml, IQR: 0.16–95.2; P = 0.68; Figure 1A). Here, IFNG is linked to myeloid sarcoma.
