Summaries for Spastic Paraplegia 45, Autosomal Recessive

UniProtKB/Swiss-Prot : 76 Spastic paraplegia 45, autosomal recessive: 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 SPG45 patients manifest mental retardation, contractures and learning disability.

MalaCards based summary : Spastic Paraplegia 45, Autosomal Recessive, also known as spg45, is related to cone-rod dystrophy and hearing loss 2 and paraplegia. An important gene associated with Spastic Paraplegia 45, Autosomal Recessive is NT5C2 (5'-Nucleotidase, Cytosolic II). Affiliated tissues include skin, bone and eye, and related phenotypes are intellectual disability and babinski sign

Disease Ontology : 12 A hereditary spastic paraplegia that has material basis in mutation in the NT5C2 gene on chromosome 10q24.
