Description

The c.160_161insT pathogenic mutation, located in coding exon 2 of the MLH1 gene, results from an insertion of one nucleotide at position 160, causing a translational frameshift with a predicted alternate stop codon (p.G54Vfs*25). 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.
