A delayed diagnosis of Arginase 1 Deficiency (ARG1‑D) can make it difficult to move forward1-2

ARG1‑D: A progressive, debilitating, inherited
metabolic disease3-5

Arginase 1 Deficiency (ARG1-D) is associated with the persistent
elevation of plasma arginine and, when left undiagnosed,
may lead to significant morbidity and early mortality.6-9

High levels of plasma arginine in childhood may progress to
cause debilitating complications in adulthood1,4,7
