Fanconi anemia (FA) is a chromosomal instability disorder inherited as an autosomal- or X-chromosomal recessive trait due to germline mutations in one of 15 FA genes (FANCA/B/C/D1/D2/E/F/G/I/J/L/M/N/O/P) involved in the DNA repair pathway (1). This evidence concerns the gene FANCA and Friedreich ataxia.
