" /> Spastic paraplegia 10, autosomal dominant - CISMeF





Preferred Label : Spastic paraplegia 10, autosomal dominant;

Symbol : SPG10;

CISMeF acronym : SPG10;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Spastic paraplegia 10 with or without peripheral neuropathy;

Description : SPG10 is an autosomal dominant neurologic disorder with variable manifestations. Some patients have onset of a 'pure' spastic paraplegia, with lower limb spasticity, hyperreflexia, extensor plantar responses, and variable involvement of the upper limbs beginning in childhood or young adulthood. Some patients show distal sensory impairment, which can be part of the 'pure' phenotype. However, some patients also show an axonal sensorimotor peripheral neuropathy with distal sensory impairment and distal muscle atrophy reminiscent of Charcot-Marie-Tooth disease type 2 (see, e.g., CMT2A, 118210). Rarely, patients with KIF5A mutations may have additional neurologic features, including parkinsonism or cognitive decline, consistent with a 'complicated' phenotype. Spastic paraplegia and peripheral neuropathy in isolation may represent extreme ends of the phenotypic spectrum of KIF5A mutations (summary by Goizet et al., 2008 and Crimella et al., 2012).;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the kinesin-5A gene (KIF5A, 602821.0001);

Prefixed ID : #604187;
