Arylsulfatase A deficiency
Overview
Arylsulfatase A deficiency is a genetic disorder that affects how the body breaks down certain substances. This condition is caused by a mutation in the ARSA gene, which leads to a shortage of the enzyme arylsulfatase A. This enzyme is responsible for breaking down a type of molecule called sulfatides. When sulfatides build up in the body due to the enzyme deficiency, it can cause damage to the myelin sheath that surrounds nerve cells in the brain and spinal cord.
The symptoms of Arylsulfatase A deficiency can vary widely, but often include problems with motor skills, muscle weakness, seizures, and intellectual disability. This disorder is inherited in an autosomal recessive pattern, meaning that a person must inherit two copies of the mutated gene (one from each parent) to have the condition. While there is no cure for Arylsulfatase A deficiency, treatment options focus on managing symptoms and supportive care. Early diagnosis and intervention can help improve the quality of life for individuals with this condition.
