Autosomal recessive spastic paraplegia type 23 (SPG23) is a rare, complex type of hereditary spastic paraplegia that presents in childhood with progressive spastic paraplegia, associated with peripheral neuropathy, skin pigment abnormalities (i.e. vitiligo, hyperpigmentation, diffuse lentigines), premature graying of hair, and characteristic facies (i.e. thin with ''sharp'' features). The SPG23 phenotype has been mapped to a locus on chromosome 1q24-q32.
