The molar ratios that may reflect the functioning of HSD11B1 whose values were significantly lower (n = 0), showed no significant change (n = 1), and were significantly higher in patients (n = 2) (p = 0.258 Wilcoxon’s test); no significant trend related to MS was found, possibly due to the low number of events (2/1/0, p = 0.258). This evidence concerns the gene HSD11B1 and myeloid sarcoma.
