Hereditary spastic paraplegia type 35 (SPG35) is a rare disorder characterized by progressive spasticity. Mutations in the fatty acid 2-hydroxylase (FA2H) gene in different loci are responsible for phenotypic variability. We aimed to define the phenotype of SPG35 linked to a novel homozygous mutation c.160_169dup (p.Asp57Glyfs*48) in the FA2H gene, and compared with the clinical characteristics and neuroimaging findings of the patients with mutation in the FA2H gene. We describe a 5-year-old boy presenting with spastic paraplegia. He developed a rapid progressive spastic paraplegia and loss of ambulation at an early age, despite the absence of accompanying seizure, neuropathy, cognitive impairment, speech disturbance, and optic atrophy. Neuroimaging revealed white matter changes without brain iron accumulation. A duplication variation; leading to a truncated protein c.160_169dup in the FA2H gene was found on the homozygous state. A homozygous mutation c.160_169dup in the FA2H gene, which resulted in SPG35 phenotype, may present with rapid progressive spastic paraplegia at an early age.
