Complement and Coagulation Mediated TMA (aHUS) Genetic Analysis
Also known as: thrombotic microangiopathy, Thrombotic Thrombocytopenic Purpura, TMA, TTP
Use
Diagnostic testing; pharmacogenetics
Special Instructions
Not provided.
Limitations
This analysis may not consistently detect mosaicism or confirm large chromosomal aberrations that do not involve changes in copy number such as rearrangements and inversions. The assay will not detect repeat expansions, and certain technical constraints may lead to false positives or negatives. Factors such as pseudogene interference, homologous regions, and sample labeling errors may also affect test accuracy. Interpretation relies on current variant databases, and clinical significance may change over time.
