Goldmann-favre Syndrome
Disease Details
Family Health Simplified
- Description
- Goldmann-Favre Syndrome is a rare retinal disorder characterized by progressive vision loss, night blindness, retinal degeneration, and abnormal accumulation of fluid in the retina.
- Type
- Goldmann-Favre syndrome is a **rare inherited retinal degenerative disorder**. Its type of genetic transmission is **autosomal recessive**.
- Signs And Symptoms
-
Goldmann-Favre syndrome, also known as enhanced S-cone syndrome, is a rare inherited retinal disorder. Here are the signs and symptoms:
- **Night blindness (nyctalopia):** Difficulty seeing in low light or darkness.
- **Photophobia:** Sensitivity to bright light.
- **Degenerative changes in the retina:** Including cystic macular degeneration and peripheral pigmentary changes.
- **Abnormal electroretinogram (ERG):** An enhancement of the S-cone response and reduced responses from other types of cone and rod photoreceptors.
- **Reduced visual acuity:** Progressive worsening of vision over time.
- **Peripheral vision loss:** Progressive constriction of the visual field.
- **Vitreous alterations:** Including the presence of vitreous veils or strands.
The disease typically begins in childhood and progresses over time. It is associated with mutations in the NR2E3 gene. - Prognosis
-
Goldmann-Favre Syndrome, also known as Enhanced S-Cone Syndrome, is a rare genetic disorder that primarily affects the eyes. The prognosis for this condition can vary for each individual. Generally:
- **Prognosis**: Vision loss is progressive, and individuals often experience a significant reduction in visual acuity over time. Night blindness, peripheral vision loss, and sensitivity to light are common features. Regular monitoring by an ophthalmologist and supportive measures can help manage symptoms, but there is currently no cure.
- **Nan**: There seems to be a misunderstanding, as "nan" usually refers to a value that is not a number. If additional specific information is needed, please clarify. - Onset
- Goldmann-Favre syndrome is a rare genetic disorder that typically manifests in early childhood or adolescence. It is characterized by a progressive degeneration of the retina, leading to visual impairment. Significant symptoms often become noticeable during the first decade of life.
- Prevalence
- The prevalence of Goldmann-Favre Syndrome is not precisely known, but it is considered a rare genetic disorder. It affects a very small fraction of the population. Specific prevalence rates are not well-documented due to its rarity.
- Epidemiology
- Goldmann-Favre syndrome, also known as enhanced S-cone syndrome, is a very rare hereditary retinal degenerative disorder. Due to its rarity, precise epidemiological data are not well-established. The condition affects both males and females and can occur in various ethnic groups. It is typically inherited in an autosomal recessive manner, which means that both copies of the gene in each cell have mutations.
- Intractability
- Goldmann-Favre syndrome, also known as enhanced S-cone syndrome, is a rare inherited retinal disorder. Currently, it is considered intractable, meaning there is no known cure or highly effective treatment. Management focuses on alleviating symptoms and preserving vision as much as possible through supportive measures. Regular monitoring by an eye specialist is essential for managing complications and maintaining the best possible quality of life.
- Disease Severity
- Goldmann-Favre syndrome, also known as enhanced S-cone syndrome, is a rare inherited retinal dystrophy. It often leads to severe vision problems, including night blindness, peripheral vision loss, and eventual deterioration of central vision. The severity of the disease can vary, but it generally progresses over time, potentially leading to significant visual impairment or blindness in severe cases.
- Pathophysiology
-
Goldmann-Favre syndrome, also known as Enhanced S-Cone Syndrome, is a rare inherited retinal dystrophy characterized primarily by night blindness (nyctalopia) and abnormalities in the retinal structure and function. Pathophysiologically, the syndrome is associated with mutations in the NR2E3 gene, which plays a crucial role in the development and maintenance of retinal cells.
The primary defect lies in abnormal development and function of the photoreceptors, particularly the S-cones (short-wavelength cones). The mutation leads to an overabundance of these S-cones and a corresponding lack of rod cells, which are critical for vision in low-light conditions. This imbalance disrupts normal retinal circuitry and visual processing, leading to the characteristic vision problems and retinal changes observed in patients. - Carrier Status
- Goldmann-Favre syndrome is a rare genetic disorder associated with mutations in the NR2E3 gene. Carrier status is relevant to individuals who possess one mutated copy of the gene and one normal copy. These carriers typically do not exhibit symptoms but can pass the mutated gene to their offspring. If both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit two mutated copies, leading to the onset of Goldmann-Favre syndrome.
- Mechanism
-
Goldmann-Favre syndrome, also known as enhanced S-cone syndrome, is a rare inherited retinal dystrophy.
**Mechanism:**
The syndrome primarily affects the retina, leading to disturbances in night vision and peripheral vision, as well as increased sensitivity to blue light. It is characterized by an abnormal increase in S-cone (short-wavelength, blue light-sensitive cone) activity, leading to disrupted photoreceptor function.
**Molecular Mechanisms:**
Goldmann-Favre syndrome is typically caused by mutations in the NR2E3 gene, located on chromosome 15q23. The NR2E3 gene encodes a nuclear receptor that is important for the proper development and function of rod photoreceptors and the suppression of excess S-cones. Mutations in the NR2E3 gene result in a malfunctioning protein, which leads to an overabundance of S-cones and underdevelopment or dysfunction of rods, causing the visual disturbances observed in the syndrome. - Treatment
-
Goldmann-Favre Syndrome is a rare genetic disorder that affects the retina. Treatment options primarily focus on managing symptoms and improving quality of life. Measures may include:
1. **Low Vision Aids:** Utilize magnifying glasses, special lenses, or other visual aids to help improve vision.
2. **Regular Monitoring:** Frequent eye examinations to monitor the condition and adjust aids as necessary.
3. **Genetic Counseling:** For affected individuals and their families to understand the inheritance pattern and implications.
Currently, there is no cure for Goldmann-Favre Syndrome, and treatments aim to optimize remaining vision and quality of life. - Compassionate Use Treatment
-
Goldmann-Favre syndrome, also known as enhanced S-cone syndrome (ESCS), is a rare inherited retinal disorder. There are no specific compassionate use treatments, off-label, or experimental treatments with definitive proven efficacy for this condition. However, some general approaches are being investigated:
1. **Gene Therapy:** Research is ongoing in gene therapy as a potential treatment. Although not yet available for routine clinical use, experimental studies have shown promise in correcting genetic defects in the retina.
2. **Cystoid Macular Edema Management:** For associated complications like cystoid macular edema, treatments used for similar retinal conditions may be applied off-label. These include carbonic anhydrase inhibitors (e.g., acetazolamide) and intravitreal injections of corticosteroids or anti-VEGF agents.
It's important for patients to be closely monitored by a retinal specialist who can provide the most up-to-date information on potential clinical trials and emerging therapies. - Lifestyle Recommendations
