Overview
X-linked pure spastic paraplegia is a rare inherited neurological condition that primarily affects the nerves controlling the legs. It belongs to a group of disorders called hereditary spastic paraplegias (HSPs), which are characterized by progressive stiffness (spasticity) and weakness in the lower limbs. The word "pure" means that the main symptoms are limited to the legs, without significant involvement of other body systems like vision, hearing, or thinking ability. Because this form is X-linked, the genetic change responsible sits on the X chromosome. This means it mostly affects males, while females may be carriers who are unaffected or have milder symptoms. Over time, people with this condition notice increasing difficulty walking due to tightness and weakness in the leg muscles. The stiffness tends to get worse gradually over years. There is currently no cure for X-linked pure spastic paraplegia. Treatment focuses on managing symptoms and maintaining mobility for as long as possible. Physical therapy, stretching exercises, and medications that reduce muscle spasticity — such as baclofen or tizanidine — are commonly used. Assistive devices like braces, walkers, or wheelchairs may become necessary as the disease progresses. Research into gene-based therapies is ongoing but no specific disease-modifying treatment is yet available.
Key symptoms:
Progressive leg stiffness (spasticity)Weakness in the legsDifficulty walkingIncreased muscle tone in the lower limbsExaggerated reflexes in the legsToe walking or dragging feetBalance problemsLeg muscle crampsFatigue in the legs after walkingUrinary urgency or frequency in some cases
X-linked recessive
Carried on the X chromosome; typically affects males more than females
Variable
Can begin at different ages, from infancy through adulthood

How is X-linked pure spastic paraplegia inherited?
X-linked pure spastic paraplegia follows a x-linked recessive inheritance pattern. Genetic counseling can help families understand recurrence risk and testing options.
