| 610357 | OMIM | Spastic paraplegia 30 (SPG30) | 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. Some SPG30 patients have a pure form of the disorder, limited to spastic paraplegia, whereas others may have a complicated form that includes additional features such as cognitive dysfunction, learning disabilities, peripheral sensorimotor neuropathy, urinary sphincter problems, and/or cerebellar atrophy. SPG30 is characterized by onset in the first or second decades of unsteady spastic gait and hyperreflexia of the lower limbs. Inheritance can be autosomal dominant or autosomal recessive. The disease is caused by variants affecting the gene represented in this entry. |
| 614255 | OMIM | NESCAV syndrome (NESCAVS) | An autosomal dominant neurodegenerative disorder with variable manifestations. Main features are delayed psychomotor development, progressive spasticity, intellectual disability, speech delay, and learning disabilities. Some patients never achieve ambulation. Additional variable features are cortical visual impairment, often associated with optic atrophy, axonal peripheral neuropathy, seizures, dysautonomia, ataxia, and dystonia. Brain imaging often shows progressive cerebellar atrophy and thin corpus callosum. Disease onset is in infancy or early childhood. The disease is caused by variants affecting the gene represented in this entry. |
| 614213 | OMIM | Neuropathy, hereditary sensory, 2C (HSN2C) | A neurodegenerative disorder characterized by onset in the first decade of progressive distal sensory loss leading to ulceration and amputation of the fingers and toes. Affected individuals also develop distal muscle weakness, primarily affecting the lower limbs. The disease is caused by variants affecting the gene represented in this entry. |
