Abstrakt: Fanconi anaemia (FA) is a rare autosomal recessive disorder associated with diverse clinical symptoms, increased chromosomal instability and a marked hypersensitivity to crosslinking agents. At least five complementation groups have been defined, the gene for group C (FAC) being the only FA gene cloned thus far. Several sequence variations have been detected in FA patients, whose assignment to group C, however, had not been ascertained by complementation studies. Using a functional assay, in which we tested the capacity of a variant sequence to correct the defect in FA-C lymphoblasts, we provide evidence for the pathogenic status of 1806insA and R548X and for non-pathogenicity of D195V.
