Comment:

The c.561dupG pathogenic mutation, located in coding exon 3 of the LMNA gene, results from a duplication of G at nucleotide position 561, causing a translational frameshift with a predicted alternate stop codon (p.L188Afs*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.
