We report two patients with very severe congenital dyserythropoietic anemia presenting with hydrops foetalis, previously classified as "atypical" CDAs since they presented CDAII-like erythroblastic morphological features lacking other diagnostic CDAII markers. Molecular characterization of SEC23B gene, recently described as responsible of CDAII, revealed the presence of Glu109Lys/Arg701Cys and Glu109Lys/Cys66Tyr mutations, respectively. This finding leads to a re-classification of these cases and underlines phenotypic heterogeneity of CDAII, demonstrating for the first time that CDAII may be associated with hydrops foetalis and intrauterine death.
