This percentage was lower than the percentage of Black individuals with iCCA diagnosed between 2004 and 2015 in the United States (~8.4%).2 Notably, the current study demonstrated that IDH1 mutations were more frequently identified among White (20.8%) versus Asian (17.8%) or Black patients (5.6%), whereas FGFR2 alterations were more frequently observed among Black individuals (27.8%). This evidence concerns the gene IDH1 and infantile convulsions and choreoathetosis.
