A new family with spastic paraplegia type 51 and novel mutations in AP4E1.

ABSTRACT:

Background

Autosomal recessive mutations in the AP-4 (adaptor protein complex 4) complex subunit ϵ - 1 (AP-4E1) gene on chromosome 15q21.2 are known to cause spastic paraplegia 51 (SPG51). The exact phenotype of SPG51 remains poorly characterized, because only a few families have been reported as carriers of the mutation. In addition, a previous study identified an autosomal dominant mutation in the AP4E1 gene as being associated with persistent stuttering. The aim of the current study was to characterize the phenotype of a paediatric patient with an identified novel AP4E1 mutation presenting with significant psychomotor retardation, intellectual disability and paraplegia.

Methods

Magnetic resonance imaging was used to identify hypoplasia of the corpus callosum. The DNA samp
