Final answer:
Short telomere disease is a condition characterized by the presence of shortened telomeres in cells, leading to various clinical features such as bone marrow failure, pulmonary fibrosis, liver disease, and immune system dysfunction.
Step-by-step explanation:
Short telomere disease is a condition characterized by the presence of shortened telomeres in cells. Telomeres are protective caps at the ends of chromosomes that shorten with each cell division. When telomeres become too short, cells can no longer divide properly, leading to various clinical features. Some consistent clinical features of short telomere disease include bone marrow failure, pulmonary fibrosis, liver disease, and immune system dysfunction.
