Fanconi anemia (FA) is an inherited bone marrow failure syndrome characterized by pancytopenia, predisposition to malignancy, and physical abnormalities including short stature, microcephaly, developmental delay, café-au-lait skin lesions, and malformations belonging to the VACTERL-H association. Diagnosis is usually made in childhood, although diagnostic delays and variable disease manifestations are common and some individuals may be diagnosed with FA in adulthood.
