Hunter Syndrome, clinically known as Mucopolysaccharidosis Type II (MPS II), stands as a rare, X-linked inherited lysosomal storage disorder, primarily characterized by a severe deficiency or absence of the iduronate-2-sulfatase (IDS) enzyme. This critical enzymatic defect leads to the progressive accumulation of complex sugar molecules, specifically glycosaminoglycans (GAGs) dermatan sulfate and heparan sulfate, within lysosomes across various cell types throughout the body. The relentless accumulation of these undegraded GAGs results in widespread cellular dysfunction and tissue damage, manifesting as a broad spectrum of clinical symptoms that progressively affect multiple organ systems including the skeletal system, respiratory and cardiovascular systems, liver and spleen, and notably, the central nervous system, leading to a significant impact on patients' quality of life and life expectancy. The disease presentation can vary widely in severity, from attenuated forms with a slower progression and milder symptoms to severe forms characterized by rapid neurocognitive decline.
The core therapeutic objective in Hunter Syndrome treatment revolves around either replacing the missing or deficient IDS enzyme or addressing the downstream effects of GAG accumulation. Enzyme Replacement Therapy (ERT) represents the cornerstone of current treatment strategies, involving the regular intravenous administration of a recombinant form of the human IDS enzyme (elosulfase alfa). This exogenous enzyme is designed to be taken up by cells, enter lysosomes, and metabolize the accumulated GAGs, thereby reducing their harmful effects and improving clinical outcomes. Beyond ERT, major applications extend to emerging modalities such as gene therapy, which seeks to deliver a functional copy of the IDS gene to the patient's cells for endogenous enzyme production, and substrate reduction therapy, which aims to decrease the synthesis of GAGs. These treatments are essential for mitigating the diverse symptoms, improving physical capabilities, and in some cases, stabilizing or slowing the progression of neurocognitive symptoms, thereby offering significant benefits such as enhanced physical functionality, reduced organomegaly, alleviation of respiratory issues, and an improved overall prognosis for affected individuals.
