Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
1. Liver biopsy documenting alanine-glyoxylate aminotransferase (AGT) activity below the normal reference range confirming PH type 1 OR Liver biopsy documenting glyoxylate reductase/hydroxypyruvate reductase (GR/HPR) activity below the normal reference range confirming PH type 2
2. Molecular genetic analysis (DNA testing) confirming mutations known to cause PH type 1, PH type 2, or PH type 3
3. Urinary oxalate excretion of greater than 0.8 mmol/1.73 m2/day (\>70 mg/1.73 m2/day) in the absence of a identifiable causes of secondary hyperoxaluria, including gastrointestinal disease known to cause enteric hyperoxaluria
4. A patient in end stage kidney failure, in whom neither a liver biopsy nor mutational analysis are available must have: (a) A plasma oxalate concentration of greater than 60 umol/L and a kidney biopsy confirming extensive oxalate deposits OR (b) Evidence of systemic oxalosis
5. Participants in the previous protocol "Tissue Bank of Urine, Blood, and Tissue Samples Collected from the Patients with Primary Hyperoxaluria" 'Mayo IRB #' #80-04. They have already consented to bank their samples and that consent will serve to enroll them in this study.
* Diagnosis of Dent disease meeting one or more of the following criteria:
1. Identified mutation of the gene that encodes for chloride exchange transporter 5 (CLCN5)
2. Low molecular weight proteinuria and hypercalciuria
3. Low molecular weight proteinuria and nephrocalcinosis
* Diagnosis of APRT disease meeting one or more of the following criteria:
1. Suspected dihydroxyadeninuria and absent APRT enzyme activity measured in red blood cells (RBCs).
2. Homozygosity, or compound heterozygosity, for known disease-causing APRT mutations.
3. Passage of dihydroxyadenine stones (confirmed with stone analysis).
* Diagnosis of Cystinuria meeting one or more of the following criteria:
1. Stone analysis demonstrating that the stone contains cystine
2. Increased urinary cystine excretion (\>250 mg/gm creatinine)
* Relative of someone with confirmed primary hyperoxaluria, Dent disease, APRT deficiency (also known as dihydroxyadeninuria), or cystinuria
2. Unwilling or unable to provide consent/assent.
