Cystinosis

Overview

Cystinosis is a rare genetic disorder. It occurs when the body lacks a specific protein responsible for transporting the amino acid cystine out of cells. Without this protein, cystine builds up inside the cells and forms crystals that can damage organs and tissues, especially the kidneys and eyes. Cystinosis is a complex condition that requires lifelong management, including medications to help remove excess cystine from the body and prevent complications like kidney failure and vision problems.

Individuals with cystinosis may experience symptoms such as excessive thirst and urination, poor growth, kidney stones, and sensitivity to light. Diagnosis is often made through genetic testing and measuring cystine levels in white blood cells. Treatment focuses on managing symptoms and preventing complications through medications, dietary adjustments, and regular monitoring by healthcare providers. Early detection and intervention are crucial in improving outcomes for individuals with cystinosis.
