Fanconi dysplasia

Fanconi anemia (FA) is an autosomal recessive genetic disorder characterised clinically by progressive bone marrow failure, skeletal deformities and a predisposition to neoplasia. Patient cells manifest an extreme chromosomal instability and hypersensitivity to polyfunctional alkylating agents. It is assumed that the basic defect is related to the repair of DNA damage, in particular that of so-called DNA crosslinks. Currently there are eight complementation groups in FA (FA-A-FA-H) which indicates that at least eight independent genes can lead to FA. Three of these genes have been identified: FANCA, FANCC and FANCG. (from PMID 10472548)
