Dyskeratosis congenita is a rare genetically heterogeneous disorder characterized by bone marrow failure and premature ageing. Current knowledge on clinical manifestations, molecular pathomechanisms, diagnostic criteria and therapeutic possibilities of patients with dyskeratosis congenita are described. Mutation analysis of the gene encoding for dyskerin revealed the c.IVS2-5C>G splice site mutation. The importance of early diagnosis in order to prevent severe invasive infections and non-infectious complications is emphasized. Family screening is important to identify carriers as prenatal genetic diagnosis conveys great benefits for family planning.
