Novel inactivating mutations of FANCC in Brazilian patients with Fanconi anemia.

Abstract

We have identified three novel FANCC mutations, a truncating single base insertion in exon 4 (c.455_456dupA), a point mutation in exon 13 (c.1390C>T), and a splice site mutation leading to deletion of exon 9, in two Brazilian FA-C patients, each a compound heterozygote. Using complementation analyses, we confirmed that two of these mutations inactivate the function of the FANCC protein. 2006 Wiley-Liss, Inc.
