Hereditary cancer-predisposing syndrome Pathogenic:1
The c.3240delA variant, located in coding exon 12 of the PALB2 gene, results from a deletion of one nucleotide at nucleotide position 3240, causing a translational frameshift with a predicted alternate stop codon (p.E1081Rfs*14). This alteration occurs at the 3' terminus of thePALB2 gene, is not expected to trigger nonsense-mediated mRNA decay, and only impacts the last 106 amino acids of the protein. However, premature stop codons are typically deleterious in nature, and these 3' amino acids are part of the functionally critical WD40 domain that is necessary for PALB2 function, stability, and interaction with BRCA2 (Oliver AW et al. EMBO Rep., 2009 Sep;10:990-6). Based on the majority of available evidence to date, this variant is likely to be pathogenic. -
