Brief Summary
Background: Bone marrow failure diseases are rare. Much is known about the diseases at the time of diagnosis, but long-term data about the effects of the diseases and treatments are lacking. Researchers want to better understand long-term outcomes in people with these diseases. Objective: To follow people diagnosed with acquired or inherited bone marrow failure disease and study the long-term effects of the disease and its treatments on organ function. Eligibility: People aged 2 years and older who have been diagnosed with acquired or inherited bone marrow failure or Telomere Biology Disorder. First degree family members may also be able to take part in the study. Design: Participants will be screened with a medical history, physical exam, and blood tests. They may have a bone marrow biopsy and aspiration. For this, a large needle will be inserted in the hip through a small cut. Marrow will be drawn from the bone. A small piece of bone may be removed. Participants may also be screened with some of the following: Cheek swab or hair follicle sample Skin biopsy Urine or saliva sample Evaluation by disease specialists (e.g., lung, liver, heart) Imaging scan of the chest Liver ultrasounds Six-Minute Walk Test Lung function test Participants will be put into groups based on their disease. They will have visits every 1 to 3 years. At visits, they may repeat some screening tests. They may fill out yearly surveys about their medicines, transfusions, pregnancy, bleeding, and so on. They may have other specialized procedures, such as imaging scans and ultrasounds. Participation will last for up to 20 years. ...
Eligibility Criteria
* INCLUSION CRITERIA: To be eligible to participate in this study, an individual must meet all of the following criteria. Subjects and their family members who undergo screening but ultimately do not meet criteria for cohorts 1-5 will be removed from the study. Subjects may forgo screening and sign directly onto cohorts 1-5 if they meet criteria based on either prior NIH testing or external examinations. Family members will only be asked to be screened for participation onto this study after confirmation of eligibility by an affected participant. Cohorts 1-4 * Age \>=2 years * Diagnosis of acquired or inherited bone marrow failure or ineffective hematopoiesis or TBD (see below for cohort 3 specific criteria) * Ability and willingness to come to the NIH CC for consultation and testing * Ability of subject or Legally Authorized Representative (LAR) to understand the investigational nature of the protocol and their willingness to sign a written informed consent document. * For cohort 3 - TBD: Presence of a pathogenic, likely pathogenic, or known family mutation in a telomere maintenance gene OR If mutation negative or VUS, telomere length \<10th percentile in lymphocytes with at least two clinical features: 1) cytopenia (Hb \<10g/dL or ANC \<1.5x10\^9 or platelets \<100), 2) documented liver fibrosis by histology OR abnormal liver US / fibro scan consistent with fatty liver or fibrosis), 3) documented pulmonary fibrosis by histology / radiology OR PFTs showing FEV1 \<80% or DLCO \<60%, 4) family history of: marrow failure, myeloid malignancy, liver fibrosis or lung fibrosis. Cohort 5 * Age \>= 2 years * First degree family member with a known or suspected inherited bone marrow failure syndrome from a patient enrolled on this or another NIH protocol as determined by a PI or AI * Ability and willingness to safely provide blood, buccal swab, or fibroblasts for testing as stated by subject * Ability of subject or Legally Authorized Representative (LAR) to understand the investigational nature of the protocol and the willingness to sign a written informed consent document. EXCLUSION CRITERIA: -None
