Published: July 2024

Introduction: Spastic paraplegia (SPG) is a heterogenous group of neurodegenerative disorders, that may include ocular involvement. Here we report the clinical data of a patient with late-onset Kjellin syndrome, a peculiar form of hereditary SPG with macular dystrophy.

Materials And Methods: Clinical, functional and multimodal retinal imaging data were collected. Genetic testing was performed by Whole Exome Sequencing (WES).

Results: A 52-year-old female patient with SPG of unknown origin was referred for a progressive visual acuity loss. Multimodal fundus imaging revealed a peculiar macular dystrophy. Given the specific association of macular dystrophy and SPG, a Kjellin syndrome was suspected and genetic testing performed. WES revealed biallelic pathogenic variants in , co-segregating with disease in the family.

Conclusion: Careful ophthalmological examination prompted the diagnosis and guided molecular testing. This case underlines the importance of a neuro-ophthalmologic assessment in patients with SPG.

In the field of hereditary spastic paraplegia (HSP), progress in molecular diagnostics needs to be translated into robust phenotyping studies to understand genetic and phenotypic heterogeneity and to support interventional trials. ZFYVE26-associated hereditary spastic paraplegia (HSP-ZFYVE26, SPG15) is a rare, early-onset complex HSP, characterized by progressive spasticity and a variety of other neurological symptoms. While prior reports, often in populations with high rates of consanguinity, have established a general phenotype, there is a lack of systematic investigations and a limited understanding of age-dependent manifestation of symptoms.

SPG15 is a hereditary spastic paraplegia subtype caused by mutations in Spastizin, a protein encoded by the ZFYVE26 gene. Spastizin is involved in autophagosome maturation and autophagic lysosome reformation and SPG15-related mutations lead to autophagic lysosome reformation defects with lysosome enlargement, free lysosome depletion and autophagosome accumulation. Symptomatic and rehabilitative treatments are the only therapy currently available for patients.

Hereditary spastic paraplegia type 15 (HSP15) is a neurodegenerative condition caused by the inability to produce SPG15 protein, which leads to lysosomal swelling. However, the link between lysosomal aberrations and neuronal death is poorly explored. To uncover the functional consequences of lysosomal aberrations in disease pathogenesis, we analyze human dermal fibroblasts from HSP15 patients as well as primary cortical neurons derived from an SPG15 knockout (KO) mouse model.

Hereditary spastic paraplegia (HSP) is a group of rare neurodegenerative disorder with genetic and clinical heterogeneity. It has autosomal dominant (AD), autosomal recessive (AR) and X-linked forms. HSPs are clinically classified into 'pure' and 'complicated' (complex) forms.
