  • Fanconi anemia complementation group B (FANCB) [MIM:300514]: A disorder affecting all bone marrow elements and resulting in anemia, leukopenia and thrombopenia. It is associated with cardiac, renal and limb malformations, dermal pigmentary changes, and a predisposition to the development of malignancies. At the cellular level it is associated with hypersensitivity to DNA-damaging agents, chromosomal instability (increased chromosome breakage) and defective DNA repair. Some severe FANCB cases manifest features of VACTERL syndrome with hydrocephalus. {ECO:0000269 PubMed:16679491}. Note=The disease is caused by mutations affecting the gene represented in this entry.
