Marinesco-Sjögren syndrome — Clinical Guidelines

Overview

Marinesco-Sjögren syndrome (MSS) is a rare, inherited neurological disorder characterized by cerebellar ataxia, mental retardation, cataracts, and optic atrophy, often presenting with additional features like myoglobinuria and neuropathy 11 12 15.

Diagnosis

Key Features: Cerebellar ataxia, mental retardation, bilateral cataracts, optic atrophy 11 15.

Recommended Tests: Genetic testing to identify mutations in the SIL1 gene or related pathways 12.

Imaging: MRI may help in assessing neurological involvement, though specific criteria are not detailed 11.

Biopsy: Salivary gland or muscle biopsy can provide supportive evidence in some cases 10.

Management

Supportive Care: Physical therapy for ataxia, educational support for cognitive impairments 11.

Symptomatic Treatment: Corticosteroids for neuropathy complications (as seen in childhood cases) 14.

Monitoring: Regular ophthalmologic evaluations due to risk of optic atrophy 15.

Special Populations

Pediatrics: Early diagnosis crucial; corticosteroids may be considered for neuropathy 14.

Comorbidities: Management of neuropathy and other complications requires multidisciplinary care 14.

Key Recommendations

Genetic testing is essential for confirming the diagnosis of Marinesco-Sjögren syndrome (Evidence: Strong 12).

Regular ophthalmologic monitoring is recommended due to the risk of optic atrophy (Evidence: Moderate 15).

Supportive therapies, including physical therapy and educational support, are crucial for managing symptoms (Evidence: Expert opinion 11).
