In an agreement with these findings, GIST FGL2 expression was significantly associated with a low tumour mitotic count and small GIST size in the SSGXVIII series, whereas no association was found with the gender, age at the time of the diagnosis, tumour site or KIT or PDGFRA mutation (Table 2). The gene discussed is PDGFRA; the disease is gastrointestinal stromal tumor.
