Abstract Hereditary spastic paraplegias (HSPs) are neurodegenerative disorders characterized by progressive corticospinal tract degeneration and spasticity. Mutations in the CYP7B1 gene, which encodes a steroid-metabolizing enzyme, can lead to spastic paraplegia type 5A, a rare autosomal recessive HSP. Here, we report an Indian family with a novel mutation in the CYP7B1 gene.
