AUTOSOMAL RECESSIVE SPASTIC PARAPLEGIA TYPE 46


Alternate names

AUTOSOMAL RECESSIVE SPASTIC PARAPLEGIA TYPE 46 Is also known as spg46

Description

Autosomal recessive spastic paraplegia type 46 (SPG46) is a rare, complex type of hereditary spastic paraplegia characterized by an onset, in infancy or childhood, of the typical signs of spastic paraplegia (i.e. spastic gait and weakness of the lower limbs) associated with a variety of additional manifestations including upper limb spasticity and weakness, pseudobulbar dysarthria, bladder dysfunction, cerebellar ataxia, cataracts, and cognitive impairment that can progress to dementia. Brain imaging may show thinning of the corpus callosum and mild atrophy of the cerebrum and cerebellum. SPG46 is due to mutations in the GBA2 gene (9p13.2) encoding non-lysosomal glucosylceramidase.

Most common symptoms of AUTOSOMAL RECESSIVE SPASTIC PARAPLEGIA TYPE 46

  • Intellectual disability
  • Hearing impairment
  • Scoliosis
  • Ataxia
  • Nystagmus

AUTOSOMAL RECESSIVE CEREBELLAR ATAXIA WITH LATE-ONSET SPASTICITY


Alternate names

AUTOSOMAL RECESSIVE CEREBELLAR ATAXIA WITH LATE-ONSET SPASTICITY Is also known as autosomal recessive cerebellar ataxia due to gba2 deficiency

Description

Autosomal recessive cerebellar ataxia with late-onset spasticity is a rare, genetic neurodegenerative disease characterized by childhood or adolescent-onset of cerebellar ataxia with dysarthria which slowly progresses and associates pyramidal signs, including lower limb spasticity, brisk reflexes, and Babinski and Hoffman signs. Patients typically present cerebellar ataxia with development of increasing asymmetric spasticity in upper and lower limbs, and variable axonal sensory or sensorimotor neuropathy. Additional heterogeneous features, including pes cavus, scoliolis, and abnormalities of the brain (e.g. cerebral atrophy), may also be associated.

Most common symptoms of AUTOSOMAL RECESSIVE CEREBELLAR ATAXIA WITH LATE-ONSET SPASTICITY

  • Scoliosis
  • Nystagmus
  • Sensorineural hearing impairment
  • Spasticity
  • Dysphagia
