Comment:

The c.1025delG pathogenic mutation, located in coding exon 9 of the CHEK2 gene, results from a deletion of one nucleotide at nucleotide position 1025, causing a translational frameshift with a predicted alternate stop codon (p.G342Vfs*7). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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.
