Disease
SPG7_HUMAN Defects in SPG7 are the cause of spastic paraplegia autosomal recessive type 7 (SPG7) [MIM:607259. Spastic paraplegia is a degenerative spinal cord disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. SPG7 is a complex form. Additional clinical features are cerebellar syndrome, supranuclear palsy, and cognitive impairment, particularly disturbance of attention and executive functions.[1] [2] [3] [4] Note=Defects in SPG7 may cause autosomal recessive osteogenesis imperfecta (OI). Osteogenesis imperfecta defines a group of connective tissue disorders characterized by bone fragility and low bone mass. Clinical features of SPG7-related osteogenesis imperfecta include recurrent fractures, mild bone deformities, delayed tooth eruption, normal hearing and white sclera.
Function
