STAT3 and cutaneous mastocytosis: We are aware that the results of the association of genotypes with the clinicopathological aspects and survival of CM patients were obtained from a relatively small number of patients from a single country, a single genetically transformed cell line served for the majority of functional analyses of STAT3 c.-1937C>G SNV, the mechanisms by which the STAT3 c.-1937C>G SNV operates in the cell cycle were not totally determined, and functional studies for other SNVs of interest were not performed in the current study.
