Hereditary spastic paraplegia 30

Spastic paraplegia-30 (SPG30) is a neurologic disorder characterized by onset of slowly progressive spastic paraplegia in the first or second decades of life. Affected individuals have unsteady spastic gait and hyperreflexia of the lower limbs. Some patients have a 'pure' form of the disorder, limited to spastic paraplegia, whereas others may have a 'complicated' form that includes cognitive dysfunction, learning disabilities, or behavioral abnormalities, peripheral sensorimotor neuropathy, urinary sphincter problems, and/or cerebellar atrophy with thin corpus callosum on brain imaging. The phenotypic features represent a spectrum of abnormalities of the central, peripheral, and autonomic nervous system (summary by Pennings et al., 2020). For a general discussion of genetic heterogeneity of autosomal dominant spastic paraplegia, see SPG3A (182600). For a general discussion of genetic heterogeneity of autosomal recessive spastic paraplegia, see SPG5A (270800).
