PLA2G2A and mastocytosis: In this study, we have not assessed the specific PLA2 group(s) secreted in mastocytosis; however, it is reasonable to hypothesize that PLA2G2A, which is the major secreted form of PLA2 in human serum and plasma [23, 63–67], is responsible for most of the detected PLA2 activity in mastocytosis.
