摘要
Dyskeratosis congenita (DC) is a rare syndrome, characterized by cutaneous abnormalities and premature death caused by bone marrow failure. In this issue of Genes & Development, Hockemeyer and colleagues (pp. 1773 1785) report a new mouse model that reconstitutes key features of DC. Disease phenotypes are generated by a POT1b deletion in a telomerase-deficient background that accelerates the shortening of telomeres by degradation.
