Overview

Congenital disorders of the bone marrow are classified into 1) inherited bone marrow failure syndromes which are the most commonly recognized entities as “inherited bone marrow disorders"; and 2) proliferative bone marrow failure syndromes that are very rare diseases with scarce data.

Inherited Bone Marrow Failure Syndromes

Inherited bone marrow failure syndromes (IBMFS) is a heterogenous group of diseases that are characterized by bone marrow failure (defective production of RBC, WBC, and/or platelets). While some may manifest during childhood, some IBMFS may not manifest until adulthood. Differentiation between diseases based on the pattern of inheritance (X-linked vs. autosomal recessive vs. autosomal dominant) is not possible since many diseases have more than one pattern of inheritance. All inherited bone marrow failure syndromes manifest with hematological abnormalities, such as pancytopenia and findings consistent with bone marrow failure (e.g. aplastic anemia or myelodysplastic syndrome). Almost all inherited bone marrow failure syndromes are considered pre-malignant conditions and predispose to both solid and hematologic malignancies. Although classically one gene is implicated in the disease pathogenesis, novel genes are being discovered in almost all inherited bone marrow failure syndromes, demonstrating the genetic heterogeneity of these disorders. Allogenic stem cell transplantation is not a universal cure for all congenital bone marrow failure syndromes.
