Fanconi's anaemia is a rare autosomal recessive disorder characterized by progressive pancytopaenia and a cellular hypersensitivity to DNA crosslinking agents. Four genetic complementation groups have been identified so far, and here we use a functional complementation method to clone complementary DNAs that correct the defect of group C cells. The cDNAs encode alternatively processed transcripts of a new gene, designated FACC, which is mutated in group C patients. The predicted FACC polypeptide does not contain any motifs common to other proteins and so represents a new gene involved in the cellular response to DNA damage.
