Test Catalog

Test ID: AHUSP    
Complement-Mediated Atypical Hemolytic-Uremic Syndrome (aHUS)/Thrombotic Microangiopathy (TMA) Gene Panel, Varies

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

Providing a comprehensive genetic evaluation for patients with a personal or family history suggestive of complement-mediated HUS/atypical HUS (aHUS) or thrombotic microangiopathies (TMA)


Establishing a diagnosis and, in some cases, allowing for appropriate management and surveillance for disease features based on the gene involved


Identifying variants in genes encoding complement alternate pathway components and specific coagulation pathway genes known to be associated with increased risk for aHUS/TMA allowing for 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 for the genes listed on the panel.


This test uses next-generation sequencing to test for variants in the ADAMTS13, C3, CD46 (MCP), CFB, CFD, CFH, CFHR1, CFHR3, CFHR5, CFI, DGKE, PLG, and THBD genes.


This test uses Sanger sequencing to test for variants in certain exons of the following genes:

PLG Exons 1, 4, and 19

CFH Exons 20-22

CFHR1 Exons 4

CFHR3 Exons 4 and 5


Identification of a pathogenic variant may assist with prognosis, clinical management, familial screening, and genetic counseling.

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

For skin biopsy or cultured fibroblast specimens, fibroblast culture and cryopreservation testing will be performed at an additional charge. If viable cells are not obtained, the client will be notified.
