GM1 Gangliosidosis is a rare genetic disorder that affects the nervous system. It is caused by a deficiency of an enzyme called beta-galactosidase, which leads to the accumulation of harmful substances in the body's cells. The life expectancy of individuals with GM1 Gangliosidosis varies depending on the type and severity of the disease.
Infantile-onset GM1 Gangliosidosis, the most severe form, typically presents within the first few months of life and progresses rapidly. Sadly, affected children usually have a significantly reduced life expectancy, with many not surviving past early childhood.
Later-onset forms of GM1 Gangliosidosis, such as juvenile and adult-onset, have a more variable disease course. While life expectancy can be significantly impacted, individuals with these forms may survive into adulthood, albeit with significant disabilities and medical complications.
