Additional Information:

Description: (OMIM) SPG28 is an autosomal recessive neurodegenerative disorder characterized by early-onset, slowly progressive lower-limb spasticity resulting in walking difficulties. Some patients also have distal sensory impairment (summary by Tesson et al., 2012).

For a general phenotypic description ...

Clinical Description OMIM Bouslam et al. (2005) reported a consanguineous Moroccan family in which 3 members had pure spastic paraplegia with distal sensory loss in the lower limbs; 1 had mild upper limb involvement. Features included hyperreflexia of the lower limbs, ...
Molecular genetics OMIM In 3 affected members of the consanguineous Moroccan family with autosomal recessive SPG28 originally reported by Bouslam et al. (2005), Tesson et al. (2012) identified a homozygous mutation in the DDHD1 gene (614603.0001). The mutation, which was identified ...
