Summaries for Spastic Paraplegia 5a, Autosomal Recessive

OMIM : 57 Spastic paraplegia-5A is an autosomal recessive neurologic disorder with a wide phenotypic spectrum. Some patients have pure spastic paraplegia affecting only gait, whereas others may have a complicated phenotype with additional manifestations, including optic atrophy or cerebellar ataxia (summary by Arnoldi et al., 2012). The hereditary spastic paraplegias (SPG) are a group of clinically and genetically diverse disorders characterized by progressive, usually severe, lower extremity spasticity; see reviews of Fink et al. (1996) and Fink (1997). Inheritance is most often autosomal dominant (see 182600), but X-linked (see 303350) and autosomal recessive forms also occur. (270800)

MalaCards based summary : Spastic Paraplegia 5a, Autosomal Recessive, also known as spg5a, is related to spastic paraplegia 76, autosomal recessive and paraplegia. An important gene associated with Spastic Paraplegia 5a, Autosomal Recessive is CYP7B1 (Cytochrome P450 Family 7 Subfamily B Member 1). Affiliated tissues include cerebellum, skin and bone, and related phenotypes are nystagmus and dysarthria

Disease Ontology : 12 A hereditary spastic paraplegia that is characterized by progressive muscle weakness and paraplegia and has material basis in mutation in the CYP7B1 gene on chromosome 8q12.

UniProtKB/Swiss-Prot : 75 Spastic paraplegia 5A, 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.
