About Fabry Disease
Fabry disease is a rare, inherited lysosomal storage disorder caused by mutations in the GLA gene, which leads to a deficiency of the enzyme alpha-galactosidase A. This deficiency results in an accumulation of a fatty substance called globotriaosylceramide (GL-3) in the body's cells, affecting the heart, kidneys, skin, nervous system, and other organs. Fabry disease can cause a range of serious signs and symptoms, including fatigue, chronic pain, gastrointestinal issues, decreased ability to sweat, progressive kidney failure, heart complications, and increased risk of stroke.
The condition affects both males and females and can present from childhood through adulthood, often with delayed diagnosis or misdiagnosis. While Fabry disease is rare, early detection and access to appropriate treatment - such as enzyme replacement therapy or pharmacological chaperone therapy - are critical in managing symptoms and slowing disease progression.
About Alpha-mannosidosis
Alpha-mannosidosis is an ultra-rare, inherited lysosomal storage disorder caused by mutations in the MAN2B1 gene, which results in a deficiency of the enzyme alpha-mannosidase. This deficiency leads to the accumulation of oligosaccharides, within the body's cells, causing progressive damage to multiple organs and tissues. Alpha-mannosidosis can affect the musculoskeletal system, hearing, immune system, nervous system, and other organs, and is associated with a wide range of signs and symptoms, including skeletal abnormalities, impaired mobility, hearing loss, cognitive impairment, immune dysfunction, and behavioral or mental health challenges.
The condition affects both children and adults and may present with few or mild symptoms early in life, progressing over time as oligosaccharides accumulate. While alpha-mannosidosis is rare, timely diagnosis and appropriate disease management are important to help address symptoms and support long-term outcomes for affected individuals.
