The genes that have been found to be mutated in FA patients are called FANC. To date 16 distinct FANC genes (FANCA, FANCB, FANCC, FANCD1 (also known as BRCA2), FANCD2, FANCE, FANCF, FANCG, FANCI, FANCJ, FANCL, FANCM, FANCN, FANCO, FANCP, and FANCQ) have been reported [2-5]. Here, FANCB is linked to Friedreich ataxia.
