Could it Be ARG1‑D?
It is crucial to diagnose and manage ARG1‑D without delay. Here are some ways to identify the signs.
What Is ARG1‑D?
Diagnosing ARG1‑D
The Typical Journey for a
Patient With ARG1‑D
The Impact of ARG1‑D
Prolonged exposure to uncontrolled arginine levels has been associated with disease progression,1,2 and arginine levels are difficult to control with current standard of care.3-5
The Unmet Need in ARG1‑D
Detection
Why ARG1‑D Is Easily
Misdiagnosed
The Burden of ARG1‑D
Managing ARG1‑D
It is important to test for and manage ARG1‑D as early as possible,6,7 it is also important to be aware of arginine levels, whether or not symptoms appear.6,7
