Objective: To report novel mutations SEC23B gene in congenital dyserythropoietic anemia (CDA).
Methods: By direct sequencing method, we sequenced CDAN1 and SEC23B genes in a Chinese CDA II patient, presented with chronic fatigue and dark urine, as well as his family members. Serum hepcidin was assayed by mass spectrometry.
Results: We found a c.71G>A mutation and a c.74C> A mutation in the patient. In addition, a heterozygous c.55A>G mutation of HFE2 gene was found in some family members. The level of serum hepcidin of the patient was below the detection limit (<1 nmol/L).
Conclusion: Contrary with what have been reported previously in the Europe, especially in the Italy, the gene mutations identified in this case was different and novel. The two novel mutations contribute to the diagnosis of CDAII and are the first report in East Asian CDAII patients.

Hemophagocytic lymphohistiocytosis (HLH), is a fatal systemic hyperinflammatory syndrome. HLH may be due to immunosuppression, infections, cancer, or autoimmune diseases with fever and cytopenia. HLH which occurs in adult-onset Stills disease (AOSD) is called secondary HLH, also known as macrophage activation syndrome (MAS).

Background: Inactivation or mutations of FAM20C causes human Raine Syndrome, which manifests as lethal osteosclerosis bone dysplasia or non-lethal hypophosphatemia rickets. However, it is only hypophosphatemia rickets that was reported in the mice with Fam20c deletion or mutations. To further investigate the local and global impacts of Fam20c mutation, we constructed a knock-in allele carrying Fam20c mutation (D446N) found in the non-lethal Raine Syndrome.

Dyserythropoietic anemia and myopathy syndrome (DAMS) with neonatal losses was recently characterized as an autosomal recessive disorder caused by an frameshift variant in English Springer Spaniels (ESSPs). The frequency and dissemination of the mutation remained unknown. The EHBP1L1 protein is essential for muscle function, and the Rab8/10-EHBP1L1-Bin1-dynamin axis participates in nuclear polarization during the enucleation of erythroblasts.

Ineffective erythropoiesis (IE) is defined as the abnormal differentiation and excessive destruction of erythroblasts in the marrow, accompanied by an expanded progenitor compartment and relative reduction in the production of reticulocytes. It is a defining feature of many types of anemia, including beta-thalassemia. GATA1 is an essential transcription factor for erythroid differentiation, known to be implicated in hematological conditions presenting with IE, including beta-thalassemia and congenital dyserythropoietic anemia.
