Abstract
Fanconi anemia (FA) is a genetic disease with birth defects, bone marrow failure, and cancer susceptibility. To date, genes for five of the seven known complementation groups have been cloned. Complementation group D is heterogeneous, consisting of two distinct genes, FANCD1 and FANCD2. Here we report the positional cloning of FANCD2. The gene consists of 44 exons, encodes a novel 1451 amino acid nuclear protein, and has two protein isoforms. Similar to other FA proteins, the FANCD2 protein has no known functional domains, but unlike other known FA genes, FANCD2 is highly conserved in A. thaliana, C. elegans, and Drosophila. Retroviral transduction of the cloned FANCD2 cDNA into FA-D2 cells resulted in functional complementation of MMC sensitivity.
