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…

A toddler girl with infantile-onset Pompe disease is able to walk independently and lives with a healthy heart after receiving treatment as a baby, according to researchers who used a combination of early enzyme replacement therapy (ERT) and immunotherapy. Immunotherapy helped tone down the body’s immune…

Age and the use of an assistive device like a walker may tell how well a patient with late-onset Pompe disease will do in a six-minute walk test (6MWT), a small study suggests. The 6MWT is considered a gold standard for determining, through difficulties in walking, the severity of…

Pain is relevant but appears to be unrelated to damage to small nerve fibers in the skin of late-onset Pompe disease patients who are using enzyme replacement therapy, a study found. The study, “Small fiber involvement is independent from clinical pain in late-onset Pompe disease,” was published in…

The same common GAA gene variants that cause Pompe disease can lead to symptoms first appearing at very different ages, and this may be due to factors that modify how genes work, a study of a global database suggests. These findings “will be important for diagnosis, genetic counseling, decision making…

Adults with late-onset Pompe disease (LOPD) report worse physical health and quality of life than their counterparts with other rare diseases, a national survey in China has found. In the study, however, stronger social support — in the form of social interaction — was linked to better quality of…

A better understanding of Pompe disease-causing genetic mutations may help with early treatment intervention, even if symptoms are subtle, a small Hungarian study suggests. Researchers found that the precise localization of a mutation determines the impact on GAA enzyme activity, which in turn has been associated with disease onset.
