Background: Kufor–Rakeb syndrome (KRS) is a rare autosomal recessive neurodegenerative disorder caused by pathogenic variants in the ATP13A2 gene. It is characterized by juvenile-onset parkinsonism, cognitive decline, and neuropsychiatric manifestations.
Case Presentation: A 16-year-old boy presented with a three-year history of progressive cognitive decline, behavioural changes, speech impairment, dysphagia, and gait difficulty. Neurological examination revealed cognitive dysfunction, hypomimia, generalized rigidity, dysarthria, brisk lower-limb reflexes, and bilateral extensor plantar responses. Routine laboratory investigations and disease-specific screening tests were unremarkable. Clinical exome sequencing identified a homozygous pathogenic ATP13A2 variant, c.2629G>A (p.Gly877Arg), confirming the diagnosis of Kufor–Rakeb syndrome. Supportive multidisciplinary management was initiated.
Conclusion: This case highlights the importance of considering ATP13A2-related Kufor–Rakeb syndrome in adolescents with progressive neurocognitive decline and juvenile-onset parkinsonism. Early genetic testing can facilitate timely diagnosis, counselling, and supportive care.
Keywords: ATP13A2, Kufor–Rakeb syndrome, juvenile parkinsonism, neurodegeneration, cognitive decline, case report.
