Abstract
Telomerase is a ribonucleoprotein enzyme that is necessary for overcoming telomere shortening In human germ and stem cells. Mutations in telomerase or other telomeremaintenance proteins can lead to diseases characterized by depletion of hematopoietic stem cells and bone marrowfailure (BMF). Telomerase localization to telomeres requires an interaction with a region on the surface of the telomere-binding protein TPP1 known as the TEL patch. Here, we Identify a family with aplastic anemia and other related hematopoietic disorders in which a 1-amino-acid deletion In the TEL patch of TPP1 (ΔK170) segregates with disease. All family members carrying this mutation, but not those with wild-type TPP1..
