Description : SPG49 is an autosomal recessive complicated form of spastic paraplegia, a neurodegenerative
disorder of the corticospinal tracts. It is characterized by delayed psychomotor development,
mental retardation, and onset of spastic paraplegia in the first decade. Affected
individuals also have dysmorphic features, thin corpus callosum on brain imaging,
and episodes of central apnea, which may be fatal (summary by Oz-Levi et al., 2012).
For a general phenotypic description and a discussion of genetic heterogeneity of
autosomal recessive spastic paraplegia, see 270800.;
Inheritance : Autosomal recessive;
