glycogen

A new cell-based therapy containing a modified version of the GAA gene mutated in Pompe disease, can effectively clear out glycogen in a number of tissues, including the heart, skeletal muscles, and central nervous system (CNS), a mouse study showed. The new treatment functions as a blood stem cell…

A number of enzymes involved in synthesizing glycogen – the molecule that accumulates to toxic levels in Pompe disease – are elevated in a mouse model of the disease and these metabolic changes may contribute to the disease’s progression, a study found. In fact, the buildup of these proteins…

The U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease designation to Aro Biotherapeutics’ ABX1100, an investigational substrate reduction therapy for Pompe disease. This designation is awarded to experimental therapies for rare pediatric disorders with serious or life-threatening manifestations that primarily affect young people from birth…

AVR-RD-03, Avrobio‘s experimental blood stem cell gene therapy for classic infantile-onset Pompe disease, was found to be safe and effective in a mouse model of the disease. The findings, presented as a poster at the 2022 annual meeting of the American Society of Gene & Cell Therapy (ASGCT)…

When strangers notice the differences between my son, Cayden, and other 4-year-olds, they usually have a lot of questions. While I genuinely don’t mind taking the time to educate and inform people about infantile-onset Pompe disease, explaining things over and over can be a bit overwhelming. I can’t expect people…

AVR-RD-03, Avrobio‘s investigational gene therapy for classic infantile-onset Pompe disease, was found to reduce toxic glycogen accumulations to healthy levels in a mouse model of Pompe. These results, presented during an Avrobio Virtual R&D Day…

A skin biopsy is one of the tests that doctors can use to help diagnose Pompe disease, a rare genetic disease characterized by the buildup of complex sugar molecules called glycogen in muscle and other tissues. This buildup may interfere with function and cause the symptoms…

Electromyography (EMG) is a medical test that doctors can use to assess the health of muscles and nerves, how well they are working and communicating. An EMG may be given to diagnose late-onset Pompe disease, a rare, heritable, and progressive disorder characterized by the buildup of large sugar…

Transplanting blood stem cells modified to carry the GAA gene raised glycogen levels almost to normal across a range of organs, including the brain, and improved locomotion in a mouse model of Pompe disease, a study reported. These findings suggest that blood stem cell gene therapy, in which a patient’s…

Measuring the urinary levels of a particular sugar molecule called tetraglucose (Glc4) could be useful for diagnosing Pompe disease, a study from France suggests. The study, “Urine glucose tetrasaccharide: A good biomarker for glycogenoses type II and III? A study of the French cohort,” was published…
