The coding exon or a part of the coding exon containing the MSH2 familial mutation is amplified using specific primers and bidirectionally sequenced using a fluorescent method.
MSH2 targeted sequencing can be performed on a patient with a known familial mutation. If MHS2 sequencing that detected the familial mutation was not performed at MMGL Molecular Genetics Lab, then please send a copy of the clinical laboratory report that documents the familial mutation.
Interpretive report provided.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
This analysis will not identify mutations in the regulatory elements, deep intronic regions or coding regions of MSH2 that are not covered by this targeted test. This assay may not detect large deletion or duplication mutations and balanced translocations involving MSH2 gene.

Offsite Collection Instructions
Collect specimen in a lavender top tube. Send intact specimen within 24 hours if stored at room temperature or within 5 days if stored refrigerated. If the previous testing of the proband was not performed by the MMGL laboratory, please also provide a copy of the clinical molecular genetics report issued by the CLIA-certified testing laboratory for the proband, patient or family member in which the mutation was previously detected. Obtaining informed consent from the patient (or legally authorized representative) prior to genetic testing is strongly recommended. If desired, a UMHS Request and Consent for Genetic Testing form can be obtained from the MMGL Molecular Genetics Laboratory by contacting the MLabs Client Services Center at 800-862-7284 or online at https://mlabs.umich.edu/sites/default/files/2020-01/file/pci-mmgl_infor….
