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 and a discussion of genetic heterogeneity of autosomal recessive
spastic paraplegia, see 270800.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the DDHD domain-containing protein 1 gene (DDHD1, 614603.0001);
