How might GM1 gangliosidosis be treated?

There is currently no effective medical treatment for GM1 gangliosidosis.[1] Symptomatic treatment for some of the neurologic signs and symptoms is available, but does not significantly alter the progression of the condition.[2][3] For example, anticonvulsants may initially control seizures. Supportive treatments may include proper nutrition and hydration, and keeping the affected individual's airway open.[4]

Bone marrow transplantation was reportedly successful in an individual with infantile/juvenile GM1 gangliosidosis; however, no long-term benefit was reported. Presymptomatic cord-blood hematopoietic stem-cell transplantation has been advocated by some as a possible treatment due to its success in other lysosomal storage disorders.[1] Active research in the areas of enzyme replacement and gene therapy for the condition is ongoing but has not yet advanced to human trials.[2][3]

Neurologic and orthopedic sequelae may prevent adequate physical activity, but affected individuals may benefit from physical and occupational therapy.[1]
