Symptoms and Testing information for GLB1 Gene GM1-Gangliosidosis Genetic Test

GM1-gangliosidosis is a rare, inherited lysosomal storage disorder caused by mutations in the GLB1 gene. This gene provides instructions for making an enzyme called beta-galactosidase, which plays a crucial role in the breakdown and recycling of certain molecules within cells. When mutations in the GLB1 gene occur, the activity of beta-galactosidase is reduced or absent, leading to the accumulation of harmful substances in various tissues and organs. This accumulation causes the symptoms and physical findings associated with GM1-gangliosidosis.

Symptoms of GM1-Gangliosidosis

GM1-gangliosidosis is classified into three major types based on the age of onset and severity of symptoms: Type I (infantile), Type II (late infantile or juvenile), and Type III (adult or chronic). Each type presents a different set of symptoms.

  • Type I: Symptoms usually appear within the first six months of life and may include severe neurological impairment, developmental regression, a cherry-red spot in the eye, bone abnormalities, and distinctive facial features. Unfortunately, children with Type I often do not survive past early childhood.
  • Type II: This form is less severe than Type I, with symptoms appearing in late infancy or early childhood. Children may experience developmental delays, mild skeletal abnormalities, and difficulties with movement and coordination. The life expectancy for individuals with Type II varies.
  • Type III: The mildest form of GM1-gangliosidosis, Type III, typically presents in childhood or adolescence. Symptoms may include muscle weakness, bone deformities, and mild intellectual disability. Individuals with Type III tend to have a longer life expectancy, although they may experience health problems related to the disease.

It is important to note that the symptoms of GM1-gangliosidosis can vary widely even among individuals with the same type. Early diagnosis and intervention are crucial for managing symptoms and improving the quality of life for those affected by the condition.
