Summary
Gene diagnosis identified a peripherin/RDS mutation in a patient with atypical retinal degeneration and choroidal neovascularization (CNV), aiding accurate diagnosis and differentiating from age-related macular degeneration.
Area of Science:
- Ophthalmology
- Genetics
- Retinal Diseases
Background:
- Atypical retinal degenerative diseases can present with choroidal neovascularization (CNV).
- Accurate diagnosis is crucial to differentiate from common conditions like age-related macular degeneration (AMD) or high myopia.
Observation:
- A 47-year-old woman presented with peripheral retinal degeneration and visual field defects.
- Seven years later, she developed foveal CNV with decreased visual acuity.
- Optical coherence tomography and fluorescein angiography characterized the CNV.
Findings:
- Gene diagnosis using denaturing high performance liquid chromatography (DHPLC) identified a peripherin/RDS gene mutation (Gly167-Ser).
- This genetic finding was instrumental in diagnosing the atypical retinal degenerative disease.
Implications:
- Genetic evaluation is essential for diagnosing rare retinal disorders presenting as CNV.
- Correct diagnosis prevents misclassification as AMD or CNV associated with high myopia.
- Understanding gene mutations aids in the management of inherited retinal conditions.

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
