Monogenic Kidney Stone - Genetic Testing

This study uses genetic testing to identify inherited (monogenic) causes of kidney stones and nephrocalcinosis (calcium buildup in the kidneys). Identifying a genetic cause can help doctors better tailor treatment and understand the long-term outlook. You may be eligible if: - You are under 18 with a history of kidney stones or nephrocalcinosis, OR - You are over 18 with kidney stones/nephrocalcinosis AND additional risk factors (family history, growth problems, unusual stone composition, kidney cysts, etc.), OR - Your doctor suspects a monogenic kidney stone disease, OR - You are a family member of someone who meets the above criteria You may NOT be eligible if: - You have kidney stones but your case does not suggest a genetic (monogenic) cause - You are unwilling or unable to provide consent Talk to your doctor to see if this trial is right for you.
