Infantile-onset ascending hereditary spastic paralysis is a motor neuron disease characterized by progressive weakness and stiffness of muscles in the arms, legs, and face. Initial symptoms usually occur within the first 2 years of life and include weakness of the legs, leg muscles that are abnormally tight and stiff, and eventual paralysis of the legs. Over time, muscle weakness and stiffness travels up (ascends) the body from the legs to the head. Infantile-onset ascending hereditary spastic paralysisis caused by mutations in the ALS2 gene, and this condition is inherited in an autosomal recessive pattern.[1]
