Summaries for Spastic Paraplegia 56, Autosomal Recessive

UniProtKB/Swiss-Prot : 73 Spastic paraplegia 56, 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. Complicated forms are recognized by additional variable features including spastic quadriparesis, seizures, dementia, amyotrophy, extrapyramidal disturbance, cerebral or cerebellar atrophy, optic atrophy, and peripheral neuropathy, as well as by extra neurological manifestations. In SPG56, upper limbs are often also affected. Some SPG56 patients may have a subclinical axonal neuropathy.

MalaCards based summary : Spastic Paraplegia 56, Autosomal Recessive, also known as spg56, is related to spastic paraplegia 46, autosomal recessive and paraplegia. An important gene associated with Spastic Paraplegia 56, Autosomal Recessive is CYP2U1 (Cytochrome P450 Family 2 Subfamily U Member 1). Affiliated tissues include globus pallidus, and related phenotypes are babinski sign and lower limb hyperreflexia

Disease Ontology : 12 A hereditary spastic paraplegia that has material basis in mutation in the CYP2U1 gene on chromosome 4q25.

OMIM : 56 SPG56 is an autosomal recessive neurodegenerative disorder characterized by early-onset progressive lower-limb spasticity resulting in walking difficulties. Upper limbs are often also affected, and some patients may have a subclinical axonal neuropathy (summary by Tesson et al., 2012). For a general phenotypic description and a discussion of genetic heterogeneity of autosomal recessive spastic paraplegia, see 270800. (615030)
