Fanconi anaemia (FA) is an autosomal recessive disorder characterized by a diversity of clinical symptoms including skeletal abnormalities, progressive bone marrow failure and a marked predisposition to cancer. FA cells exhibit chromosomal instability and hyper-responsiveness to the clastogenic and cytotoxic effects of bifunctional alkylating (cross-linking) agents, such as diepoxybutane (DEB) and mitomycin C (MMC). Five complementation groups (A-E) have been distinguished on the basis of somatic cell hybridization experiments, with group FA-A accounting for over 65% of the cases analysed. A cDNA for the group C gene (FAC) was reported and localized to chromosome 9q22.3 (ref.8). Genetic map positions were recently reported for two more FA genes,
FAA
(16q24.3) and
FAD
(3p22-26). Here we report the isolation of a cDNA representing the FAA gene, following an expression cloning method similar to the one used to clone the FAC gene. The 5.5-kb cDNA has an open reading frame of 4,368 nucleotides. In contrast to the 63-kD cytosolic protein encoded by the FAC gene, the predicted
FAA
protein (M(r) 162, 752) contains two overlapping bipartite nuclear localization signals and a partial leucine zipper consensus, which are suggestive of a nuclear localization.

Using homozygosity mapping in a large consanguineous family, we have localised to chromosome 9p a further gene for the autosomal recessive, genetically heterogeneous disease Fanconi anaemia (FA). This is the fourth of at least eight FA genes to be localised to a discrete chromosomal region. Previously localised genes are
FAA
, FAC and
FAD
. By analysis of assigned families we show that the gene localised to chromosome 9p is FAF, FAG or FAH, or a new FA gene, and refine the localisation to the 21 cM region between markers D9S1678 and D9S175.

N-hydroxy-2-acetylaminofluorene (N-OH-
AAF
) was reduced to 2-acetylaminofluorene by rat liver microsomes in the presence of both NAD(P)H and
FAD
under anaerobic conditions. The microsomal reduction proceeds as if it were an enzymatic reaction. However, when the microsomes were boiled, the activity was not abolished, but was enhanced. The activity was also observed with cytochrome P450 2B1 alone, without NADPH-cytochrome P450 reductase, in the presence of these cofactors. Hematin also exhibited a significant reducing activity in the presence of both a reduced pyridine nucleotide and
FAD
. The activities of microsomes, cytochrome P450 2B1 and hematin were also observed upon the addition of photochemically reduced
FAD
instead of both NAD(P)H and
FAD
. The microsomal reduction of N-OH-
AAF
appears to be a non-enzymatic reaction by the reduced flavin, catalyzed by the heme group of cytochrome P450.
