SPG21 Gene, Old Order Amish Specific Mutation Analysis - SPG21 Gene Mutation Analysis
Mast syndrome is an autosomal recessive, complicated form of hereditary spastic paraplegias associated with dementia that has been found in the Old Order Amish population. The disease is slowly progressive with development, speech and gait disturbances noted in childhood and cerebellar and extrapyramidal abnormalities in advanced disease. The c.601dupA mutation is associated with these cases of Mast syndrome amongst the Amish. This test specifically analyzes the c.601dupA mutation in the SPG21 gene.
