Summary
Alpha-mannosidosis, a rare lysosomal storage disease, can cause late-onset retinal dystrophy. This study details two brothers with neurological symptoms and this specific ocular manifestation.
Area of Science:
- Biochemistry
- Genetics
- Ophthalmology
Background:
- Alpha-mannosidosis is a rare lysosomal storage disease resulting from alpha-mannosidase enzyme deficiency.
- It typically presents with coarse facial features, skeletal abnormalities, intellectual disability, and organomegaly.
- Ocular manifestations are infrequently reported, primarily as lenticular opacities.
Observation:
- This report focuses on two brothers exhibiting complex neurological symptoms.
- Both brothers developed late-onset retinal dystrophy.
- Ocular and neurological progression was monitored over a six-year period.
Findings:
- The study documents a rare association between alpha-mannosidosis and late-onset retinal dystrophy.
- Detailed clinical observations of neurological and ophthalmological progression in affected siblings are presented.
- The findings highlight the potential for significant visual impairment in this rare genetic disorder.
Implications:
- This case series expands the known clinical spectrum of alpha-mannosidosis.
- It underscores the importance of ophthalmological evaluation in patients with this condition.
- Further research into the pathogenesis of retinal dystrophy in alpha-mannosidosis is warranted.
