Aplastic anemia may be inherited or acquired. The distinction between these lies
not in the age of the patient, but in the clinical and laboratory diagnoses. Adult
hematologists must consider adult presentations of the inherited disorders, in
order to avoid incorrect management of their patients. Physicians for adult
patients must also realize that children with inherited disorders now survive to
transition into their care. The major inherited bone marrow failure syndromes
associated with development of pancytopenia include Fanconi anemia,
dyskeratosis congenita, Shwachman-Diamond syndrome, and amegakaryocytic
thrombocytopenia. The ages at presentation are highly variable, but often include
individuals of adult age who have previously undiagnosed Fanconi anemia or
dyskeratosis congenita. Many of the genes responsible for these disorders have
been identified (12 Fanconi anemia genes, 3 dyskeratosis congenita genes, and
1 each for Shwachman-Diamond syndrome and amegakaryocytic
thrombocytopenia). A high index of suspicion and specific testing of children or
adults with what appears to be acquired aplastic anemia may identify inherited
disorders. Correct classification of patients with aplastic anemia of any age is
mandatory for their appropriate management.

The inherited bone marrow failure syndromes are traditionally considered to be
pediatric disorders, but in fact, many of the patients now are diagnosed as adults,
and many diagnosed as children now live to reach adulthood. The most common
of these rare disorders include Fanconi anemia, dyskeratosis congenita,
Shwachman-Diamond syndrome and amegakaryocytic thrombocytopenia, which
often develop aplastic anemia and may evolve into myelodysplastic syndrome
and acute myeloid leukemia; and Diamond-Blackfan anemia, severe congenital
neutropenia, and thrombocytopenia absent radii, single cytopenias that rarely if
ever become aplastic but have increased risks of leukemia. In addition, the first
three syndromes have high risks of solid tumors: head and neck and anogenital
squamous cell carcinoma in Fanconi anemia and dyskeratosis congenita, and
osteogenic sarcoma in Diamond-Blackfan anemia. Diagnosis of a marrow failure
syndrome requires recognition of characteristic physical abnormalities when
present, and consideration of these disorders in the differential diagnosis of
patients who present with "acquired" aplastic anemia, myelodysplastic syndrome,
acute myeloid leukemia, or atypically early cancers of the types seen in the
syndromes. Ultimate proof will come from identification of pathogenic mutations
in genes associated with each syndrome.
