Overview
This study seeks to examine the effects of a heterozygous mutation of the AGXT gene in a stone forming population on endogenous oxalate production. Participants will consume a controlled low-oxalate diet and provide blood and urine samples to measure the amount of oxalate in their bodies.
Interventions
- Other Controlled Diet
Participants will consume a controlled low oxalate diet for five days.
Primary outcome measures
- Urinary Oxalate Excretion [Time frame: Baseline through Day 4]
