Description

The c.885_886insG pathogenic mutation, located in coding exon 4 of the PALB2 gene, results from an insertion of one nucleotide at position 885, causing a translational frameshift with a predicted alternate stop codon (p.M296Dfs*7). 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.
