Childhood-onset spastic paraplegia with NIPAL gene mutation

Ricardo Bien-Willner et al. J Child Neurol. 2006 Nov.

Abstract

Hereditary spastic paraplegia is a heterogeneous group of inherited neurodegenerative disorders in which the predominant clinical feature is gait disturbance owing to spasticity and weakness of the lower limbs. Autosomal dominant hereditary spastic paraplegia is the predominant form of the disorder. To date, 10 autosomal dominant hereditary spastic paraplegia gene loci and genes for 6 of them have been identified. Spastic paraplegia 6, with a typical teenage onset and considered to be one of the more severe forms of the disease, is due to mutations in the gene NIPA1. We report a childhood-onset, aggressive, spastic paraparesis in a North American family with a c.316G>A mutation of the NIPA1 gene, confirming c.316 as a mutational hot spot.
