Description

The c.395delT pathogenic mutation, located in coding exon 4 of the PALB2 gene, results from a deletion of one nucleotide at nucleotide position 395, causing a translational frameshift with a predicted alternate stop codon (p.V132Afs*45). This mutation has been reported in trans with another PALB2 mutation in an individual with Fanconi anemia (Reid S et al. Nat. Genet. 2007 Feb;39(2):162-4). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
