Comment:

The c.372_373dupTA pathogenic mutation, located in coding exon 2 of the SMAD4 gene, results from a duplication of TA at nucleotide position 372, causing a translational frameshift with a predicted alternate stop codon (p.S125Ifs*5). This variant was not reported in population-based 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.
