Cytogenetic aberrations are frequently identified in GATA2-related MDS: monosomy 7 or der(7; 1q) are the most common, found in about 41% of cases, followed by trisomy 8, identified in roughly 15% of cases among published studies (11, 20); moreover, complex karyotypes are generally very rare, whereas del5q have never been described (11, 20). Here, GATA2 is linked to myelodysplastic syndrome.
