FANCC and Friedreich ataxia: If the screening is not utilized and the search for FA mutations starts straight from MLPA and Sanger sequencing of FANCA, proceeding to FANCC and FANCG when needed, the estimated cost could range from US$ 718.50 to US$ 1209.00 with an average of US$ 905.00 considering the literature information about frequency of FA complementation groups.
