A NOVEL RLBP1 GENE MUTATION ASSOCIATED WITH RETINAL FLECKS

Area of Science:

• Ophthalmology
• Genetics
• Molecular Biology

Background:

• Fleck retina syndromes are a group of inherited retinal disorders characterized by yellowish-white deposits in the retina.
• The genotype-phenotype correlation in genetic retinal diseases is complex and not fully understood.

Purpose of the Study:

• To describe an unusual presentation of fleck retina associated with a novel mutation in the RLBP1 gene.
• To contribute to the understanding of genetic variations underlying retinal conditions.

Main Methods:

• Case report of a 25-year-old male patient with fleck retina.
• Comprehensive clinical evaluation including fundoscopic examination, multimodal imaging, and electroretinography.
• Genetic analysis to identify mutations in the RLBP1 gene.

Main Results:

• The patient presented with fundus findings consistent with benign familial fleck retina.
• Genetic testing revealed a novel mutation in the RLBP1 gene.
• The RLBP1 gene is typically associated with more severe retinal dystrophies, making this finding unusual.

Conclusions:

• This case underscores the complex genotype-phenotype relationship in flecked retina syndromes.
• Further research is needed to elucidate the pathophysiology of genetic retinal diseases and their varied presentations.
• Novel mutations in genes like RLBP1 can present with atypical phenotypes, expanding the spectrum of known retinal disorders.
