Test Catalog

Test ID: PMNSR    
Postmortem Noonan and Related Panel, Varies

Useful For Suggests clinical disorders or settings where the test may be helpful

Providing a comprehensive postmortem genetic evaluation in the setting of sudden cardiac death and suspicion for Noonan syndrome or related disorders


Identification of a pathogenic variant in the decedent, which may assist with risk assessment and predictive testing of at-risk family members

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

This test includes next-generation sequencing and supplemental Sanger sequencing to evaluate the BRAF, CBL, HRAS, KRAS, MAP2K1, MAP2K2, NRAS, PTPN11, RAF1, SHOC2, and SOS1 genes.


This test is intended for use on postmortem samples (eg, formalin-fixed, paraffin-embedded [FFPE] tissue block; dried blood spot) when whole blood is not available.


This test uses next-generation sequencing to test for variants in the BRAF, CBL, HRAS, KRAS, MAP2K1, MAP2K2, NRAS, PTPN11, RAF1, SHOC2, and SOS1 genes.  


This test may aid in the postmortem diagnosis of Noonan syndrome, LEOPARD (lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonic stenosis, abnormal genitalia, retardation of growth, and deafness) syndrome, cardiofaciocutaneous (CFC) syndrome, Costello syndrome, or a related disorder.


Identification of a pathogenic variant may assist with familial risk assessment, screening, and genetic counseling.
