Summary Summary

Fanconi anemia is an inherited condition that affects the bone marrow, resulting in decreased production of all types of blood cells. People with this condition have lower-than-normal numbers of white blood cells, red blood cells, and platelets (cells that help the blood clot). Not enough white blood cells can lead to infections; a lack of red blood cells may result in fatigue and anemia; and a decreased amount of platelets may lead to excess bleeding.^[1]^[2] Fanconi anemia can be caused by mutations in various genes. It can be inherited in an autosomal recessive, autosomal dominant or X-linked recessive fashion.^[1] Hematopoietic stem cell transplantation (HSCT) is the only curative treatment for the blood problems associated with this condition.^[1]^[2]

Diagnosis Diagnosis

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

Testing Resources

The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

Prognosis Prognosis

Allogeneic hematopoietic stem cell transplantation (HCT), a type of bone marrow transplant, has long been the primary treatment method for correcting the blood defects associated with Fanconi anemia.^[3] In general, it has been estimated that five-year survivors of HCT may have a normal to near normal life expectancy,^[4] however Fanconi anemia is a risk factor that negatively impacts survival rates. One study estimated a 58 percent 30-years survival rate for one-year survivors of HCT with Fanconi anemia.^[3]

Related Diseases Related Diseases

Related diseases are conditions that have similar signs and symptoms. A health care provider may consider these conditions in the table below when making a diagnosis. Please note that the table may not include all the possible conditions related to this disease.

Conditions with similar signs and symptoms from Orphanet
FA clinical manifestations overlap with many malformation syndromes (Dubowitz, Seckel, Holt-Oram, Baller-Gerold, thrombocytopenia-absent radius, Nijmegen breakage syndromes, VACTERL association, dyskeratosis congenita; see these terms) and diagnosis of FA is often delayed until a patient develops BMF or malignancies. FA should be considered in the differential diagnosis of all young patients with BMF of unknown etiology. Other cancer predisposition syndromes (Bloom, Rothmund-Thomson or Werner syndromes; see these terms) or syndromes with pancytopenia (Diamond-Blackfan anemia, immune pancytopenia, Pearson or Shwachman-Diamond syndromes; see these terms) should be considered.

NCATS Co-Sponsored Conferences

The Helicase and Nucleic Acid-based Machine Conference Sunday, July 21, 2019 - Friday, July 26, 2019
Location: The Steamboat Grand, Steamboat Springs, CO
Description: Malfunctions of helicases and nucleic acid-based machines are implicated in a number of rare genetic disorders. Specifically, hereditary mutations in helicase genes are linked to rare diseases including Werner Syndrome, Bloom’s Syndrome, Rothmund-Thomson Syndrome, Cockayne Syndrome, Xeroderma Pigmentosum, Trichothiodystrophy, Warsaw Breakage Syndrome, Fanconi Anemia, Dyskeratosis Congenita, Crohn’s Disease, Ophthalmoplegia, and others. This FASEB meeting, which was first held in 2001, examines the roles of these and related helicases in genome metabolism and rare diseases. The meeting is the only one of its kind to focus on the functions, interactions and structures of helicases and helicase-like motors as components of fundamentally important supramolecular machines, and it explores their regulation and key roles in uncommon genetic disorders characterized by defects in DNA repair and genomic stability. The conference brings together a diverse group of academic and industry scientists who focus on the functional roles of helicases and helicase-like motors in pathways of nucleic acid metabolism.
