Scientists hunt for genetic clues to personalize treatment for rare kidney disease
NCT ID NCT05805202
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at people with atypical hemolytic uremic syndrome (aHUS), a rare disease that damages small blood vessels and kidneys. Researchers want to understand how certain rare gene mutations cause the disease by growing cells from blood samples in the lab. The goal is to find drugs that could correct these genetic problems, leading to more personalized treatments in the future.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could point toward personalized therapies for atypical HUS based on a patient's specific genetic mutation.
- What could go wrong
- This is an observational study focused on understanding the disease, not testing a treatment. It is early-stage research, and any potential therapies would need many more years of testing.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults and children with aHUS defined by history of microangiopathic hemolytic anemia and thrombocytopenia (hematocrit (Ht) \<30%, hemoglobin (Hb) \<10 g/dL, LDH \>500 IU/L, undetectable haptoglobin, fragmented erythrocytes in the peripheral blood smear with negative Coomb's test, and platelet count \<150,000/microL), associated with acute renal failure. * Written informed consent Exclusion Criteria: * TTP (ADAMTS13 activity \<10%) * STEC-HUS (presence of stx and eae genes or Shiga-toxin in the stools and/or serum antibodies against Shiga-toxin and/or STEC LPS). * Disseminated intravascular coagulation (prolonged thromboplastin time and lower than normal fibrinogen levels).
