The most common form of autosomal recessive hereditary spastic paraplegia (HSP) is caused by mutations in SPG11/KIAA1840 gene, which encodes for spatacsin. The clinical presentation of SPG11 is characterized by cognitive impairment, peripheral neuropathy and a thin corpus callosum in brain magnetic resonance imaging. We identified a novel homozygous nonsense mutation (c.6082C>T [p.Q2028]) in exon 32 of SPG11 in Korean siblings. Our findings suggest that this novel homozygous mutation in SPG11 is associated with HSP and with dysgenesis of the corpus callosum.
