Description : Fanconi anemia (FA) is a clinically and genetically heterogeneous disorder that causes
genomic instability. Characteristic clinical features include developmental abnormalities
in major organ systems, early-onset bone marrow failure, and a high predisposition
to cancer. The cellular hallmark of FA is hypersensitivity to DNA crosslinking agents
and high frequency of chromosomal aberrations pointing to a defect in DNA repair (summary
by Deakyne and Mazin, 2011). For additional general information and a discussion of
genetic heterogeneity of Fanconi anemia, see 227650.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the BRCA2 gene (BRCA2, 600185.0009);
Neoplasia : Increased susceptibility to solid cancers; Increased susceptibility to leukemia;
Laboratory abnormalities : Chromosomal breakage induced by diepoxybutane (DEB), and mitomycin C; Multiple chromosomal breaks;
