Congenital dyserythropoietic anemias (CDAs) are a group of hereditary disorders characterized by ineffective erythropoiesis and distinct morphological abnormalities of erythroblasts in the bone marrow. Most cases of CDA, caused by a wide spectrum of mutations, have been reported from Europe and Mediterranean countries, while a few cases have been described in China. Here, we present three cases of CDA, one from one family and two from a second unrelated family, with typical morphologic features and clinical presentations. Sequence analysis of CDA-related genes revealed that the proband with CDA Ι in the first family was a compound heterozygote of CDAN1 with mutation IVS-12+2T>C and c. 3389C>T, while both probands with CDA ΙΙ in the second family were a homozygote of the SEC23B gene with mutation c.938G>A (R313H). This study suggests that more patients with CDA, sharing a phenotype and genetic background like those of European and Mediterranean origin, remain to be diagnosed and reported in China.Citation
