Stem cells, telomerase and dyskeratosis congenita.

Abstract excerpt

Dyskeratosis congenita is a rare skin and bone marrow failure syndrome caused by defective telomere maintenance in stem cells. The major X-linked form of the disease is due to mutations in a nucleolar protein, dyskerin, that is part of small nucleolar ribonucleoprotein particles that are involved in processing ribosomal RNA. It is also found in the telomerase complex, pointing to an unexpected link between these...
