Alpha Mannosidosis Treatments
Alpha-mannosidosis is an incredibly rare genetic disorder characterized by a deficiency in the enzyme alpha-mannosidase. This deficiency leads to the buildup of complex sugars (oligosaccharides) in various tissues, causing a wide range of symptoms including intellectual disability, skeletal abnormalities, and impaired immune function. Historically, treatment was limited to supportive care, but the landscape changed with the advent of Enzyme Replacement Therapy (ERT).
ERT involves the regular intravenous infusion of a recombinant form of the missing enzyme. This "replacement" enzyme helps break down the accumulated sugars, potentially slowing the progression of the disease and improving motor function and quality of life. The challenge with ERT is that it does not easily cross the blood-brain barrier, meaning it may be more effective at treating the physical symptoms of the disease than the neurological ones. This has led to ongoing research into more direct delivery methods or small-molecule therapies that can reach the…
