Dyskeratosis congenita (DC) is a severe inherited bone marrow failure syndrome with associated cutaneous and noncutaneous abnormalities. In most cases, the inheritance pattern is X-linked recessive, while autosomal dominant and autosomal recessive forms have been reported. Remarkably, all causative gene mutations identified to date share a link to telomere/telomerase biology. Moreover, dyskeratosis congenita is linked to defective ribosome biogenesis.
