The coding exons and associated, flanking splice sites of the PTPN11 gene are amplified using specific primers, and bidirectionally sequenced using a fluorescent method.
To detect the presence of PTPN11 mutations in patients with a diagnosis of Noonan syndrome, LEOPARD syndrome, and other syndromes associated with PTPN11 mutations, particularly if SOS1 (with or without KRAS) mutation analysis was previously performed, and for carrier testing in families with a known PTPN11 mutation. All coding exons and associated flanking splice sites of the PTPN11 gene will be sequenced.
Interpretive report provided.
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. Include the patient's family history, pedigree, and ethnicity on the test requisition. Obtaining informed consent from the patient 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….
