Postpartum atypical hemolytic uremic syndrome (aHUS) can be challenging to diagnose. This case reveals a novel CFHR5 deletion linked to complement dysregulation in postpartum aHUS, suggesting a role for genetic testing.
Area of Science:
- Nephrology
- Hematology
- Genetics
Background:
- Thrombotic microangiopathies (TMAs) in pregnancy and postpartum, like HELLP syndrome, TTP, and aHUS, pose diagnostic difficulties due to overlapping symptoms.
- Preeclampsia/HELLP syndrome and atypical hemolytic uremic syndrome (aHUS) can co-occur postpartum, complicating clinical management.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
