摘要: Abstract. This review summarizes both historical and more recent data on the clinical, cellular genetic features of Fanconi anemia (FA), a rare autosomal recessive disorder. FA patients are characterized by pancytopenia, congenital malformations, growth delay an increased susceptibility to development malignancies, particularly acute myelogenous leukemia. cells show chromosomal fragility, slow sensitivity DNA crosslinking agents. can be caused defects in any one at least four genes. Two general hypotheses have been proposed explain underlying defect: loss repair function or step defense toward oxygen toxicity. After many attempts clone genes, first one, that defective group C, has cloned complementation FA(C) mitomycin C diepoxybutane. gene (FACC) codes for novel protein is ubiquitously expressed. Mutations various cause identified. The concludes suggesting directions future research FA.
