Invitae RCV000196323 SCV000253779 pathogenic Lynch syndrome 2015-04-21 criteria provided, single submitter clinical testing This sequence change deletes 1 nucleotide from exon 5 of the MSH6 mRNA (c.3435delA), causing a frameshift at codon 1145. This creates a premature translational stop signal (p.Arg1145Serfs*6) and is expected to result in an absent or disrupted protein product. While this particular variant has not been reported in the literature, truncating sequence changes in MSH6 are known to be pathogenic (PMID: 24362816, 18269114). For these reasons, this variant has been classified as Pathogenic.
Invitae RCV001383571 SCV001582752 pathogenic Hereditary nonpolyposis colorectal neoplasms 2015-04-21 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. While this particular variant has not been reported in the literature, truncating sequence changes in MSH6 are known to be pathogenic (PMID: 24362816, 18269114). This sequence change deletes 1 nucleotide from exon 5 of the MSH6 mRNA (c.3435delA), causing a frameshift at codon 1145.

Ambry Genetics RCV002453724 SCV002614785 pathogenic Hereditary cancer-predisposing syndrome 2016-09-08 criteria provided, single submitter clinical testing The c.3435delA pathogenic mutation, located in coding exon 5 of the MSH6 gene, results from a deletion of one nucleotide at nucleotide position 3435, causing a translational frameshift with a predicted alternate stop codon. 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.
