| 615043 | OMIM | Spastic paraplegia 43, autosomal recessive (SPG43) | A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. SP43 is characterized by childhood onset of progressive spasticity affecting the lower and upper limbs. The disease is caused by variants affecting the gene represented in this entry. |
| 614298 | OMIM | Neurodegeneration with brain iron accumulation 4 (NBIA4) | A neurodegenerative disorder associated with iron accumulation in the brain, primarily in the basal ganglia. NBIA4 results in speech difficulty, extrapyramidal signs, oromandibular and generalized dystonia, and parkinsonism. Most patients have progressive involvement of the corticospinal tract, with spasticity, hyperreflexia, and extensor plantar responses. The disease is caused by variants affecting the gene represented in this entry. |
