Hematological abnormalities in a patient with a 22q11.2 deletion.
We report a case of a 28-year-old man carrying a 22q11.2 deletion and presenting with giant platelets, thrombocytopenia and leukocyte inclusion bodies. In our patient, platelet glycoproteins were normally expressed on membranes and platelet function was preserved. The May-Hegglin anomaly or Sebastian syndrome associated with the 22q11.2 deletion was suggested. Atypical features also included the lack of any cardiovascular defect, T cell deficit or palate anomaly, generally common with this deletion.
