GATA2 cohort. (A) The approach to defining GATA2 mutations as somatic or likely somatic. (B) Age distribution comparing patients with proven germline GATA2 mutations (n = 7) and patients with definitive (n = 38) or likely (n = 13) GATA2 mutations, based on the framework outlined in panel A. Red points indicate proven, probable, or possible-treated cases of IFD. VAF, variant allele frequency.
