Summaries for Spastic Paraplegia 12, Autosomal Dominant

UniProtKB/Swiss-Prot : 76 Spastic paraplegia 12, autosomal dominant: 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.

MalaCards based summary : Spastic Paraplegia 12, Autosomal Dominant, also known as spg12, is related to spastic paraplegia 12 and hereditary spastic paraplegia 51, and has symptoms including urgency of micturition An important gene associated with Spastic Paraplegia 12, Autosomal Dominant is RTN2 (Reticulon 2). Affiliated tissues include spinal cord, skin and bone, and related phenotypes are difficulty walking and lower limb muscle weakness

Disease Ontology : 12 A hereditary spastic paraplegia that has material basis in mutation in the RTN2 gene on chromosome 19q13.

OMIM : 58 Spastic paraplegia-12 is an autosomal dominant neurodegenerative disorder characterized by lower limb spasticity and hyperreflexia, resulting in walking difficulties. Some patients may have urinary symptoms and distal sensory impairment. The age at onset is variable and can range from childhood to adulthood (summary by Montenegro et al., 2012). For a general description and a discussion of genetic heterogeneity of autosomal dominant spastic paraplegia, see SPG3A (182600). (604805)
