Description

The p.Q657* pathogenic mutation (also known as c.1969C>T), located in coding exon 4 of the MSH6 gene, results from a C to T substitution at nucleotide position 1969. This changes the amino acid from a glutamine to a stop codon within coding exon 4. 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.
