Disease Details
Family Health Simplified
- Description
- Retinitis pigmentosa 39 (RP39) is a genetic disorder characterized by progressive vision loss due to the degeneration of the retina’s photoreceptor cells.
- Type
- Retinitis pigmentosa 39 (RP39) is a type of inherited retinal dystrophy. The genetic transmission for RP39 is autosomal recessive. This means that two copies of the mutated gene, one from each parent, are required for an individual to be affected by the condition.
- Signs And Symptoms
-
Signs and Symptoms of Retinitis Pigmentosa 39:
1. Night blindness (nyctalopia)
2. Gradual loss of peripheral vision (tunnel vision)
3. Difficulty adapting to low light conditions
4. Reduced visual acuity
5. Light sensitivity (photophobia)
6. Possible development of cataracts
7. Progressive loss of central vision in advanced stages
8. Difficulty with color perception in some cases - Prognosis
-
Retinitis Pigmentosa 39 (RP39) is a subtype of retinitis pigmentosa, a group of genetic disorders that cause progressive retinal degeneration. The prognosis for RP39 varies depending on the specific genetic mutation and individual case. Generally, individuals with RP experience a gradual decline in vision, often starting with night blindness and loss of peripheral vision, eventually leading to tunnel vision and, in severe cases, complete blindness.
There is currently no cure, but ongoing research aims to develop gene therapies and other treatments to slow down the progression of the disease. Regular monitoring by an eye care professional is essential to manage the condition and implement supportive care and adaptive strategies. - Onset
- Retinitis pigmentosa 39 (RP39) is a form of retinitis pigmentosa, a group of inherited eye diseases that cause progressive vision loss. The onset of RP39 typically occurs in adolescence or early adulthood. Symptoms may include difficulty seeing at night, loss of peripheral vision, and eventual loss of central vision as the disease progresses.
- Prevalence
- Retinitis pigmentosa 39 (RP39) is a rare genetic disorder. The exact prevalence for this specific subtype (RP39) is not well-documented, but retinitis pigmentosa as a whole affects approximately 1 in 4,000 people worldwide.
- Epidemiology
- Retinitis Pigmentosa 39 (RP39) is a rare, inherited retinal dystrophy. It is part of a larger group of genetically heterogeneous disorders known as retinitis pigmentosa, affecting approximately 1 in 4,000 people worldwide. RP39 is specifically linked to mutations in the PRPF31 gene and typically follows an autosomal dominant inheritance pattern. It begins with night blindness, progressing to loss of peripheral vision and eventually central vision, often leading to legal blindness.
- Intractability
- Retinitis pigmentosa 39 (RP39) is a genetic disorder that leads to progressive vision loss due to the degeneration of photoreceptor cells in the retina. As of now, RP39 is considered an intractable disease because there is no cure to fully stop or reverse its progression. However, advances in gene therapy, retinal implants, and other treatments are being researched to manage the symptoms and potentially slow the disease's progression.
- Disease Severity
- Retinitis pigmentosa 39 (RP39) is a form of retinitis pigmentosa, which is a group of genetic disorders that cause progressive degeneration of the retina. The severity of RP39 can vary widely among individuals but generally leads to a gradual loss of vision.

- Pathophysiology
- Retinitis Pigmentosa 39 (RP39) is a genetic disorder that affects the retina’s ability to respond to light, leading to progressive vision loss. The pathophysiology involves the degeneration of photoreceptor cells in the retina, specifically the rod cells responsible for night vision and peripheral vision. As the disease progresses, cone cells also degenerate, further impairing central vision and color perception. RP39 is usually inherited in an autosomal recessive manner and is caused by mutations in the genes that are crucial for retinal cell function and survival.
- Carrier Status
-
Retinitis Pigmentosa 39 is a form of retinitis pigmentosa, which is a group of inherited disorders affecting the retina. The carrier status for Retinitis Pigmentosa 39 would depend on its mode of genetic transmission, which can vary. Retinitis pigmentosa can be inherited in multiple patterns, including autosomal recessive, autosomal dominant, and X-linked recessive.
In the case of an autosomal recessive form, carriers have one copy of the mutated gene but typically do not exhibit symptoms. If both parents are carriers, there is a 25% chance they will have an affected child, a 50% chance their child will also be a carrier, and a 25% chance their child will not carry the mutation.
Carrier status assessment typically requires genetic testing to identify specific mutations associated with Retinitis Pigmentosa 39. - Mechanism
-
Retinitis pigmentosa 39 (RP39) is a subtype of retinitis pigmentosa, a group of genetic disorders characterized by progressive peripheral vision loss and night vision difficulties, eventually leading to central vision loss. The primary molecular mechanisms underlying RP39 involve genetic mutations that affect the function and survival of photoreceptor cells in the retina.
RP39 is associated with mutations in the gene PRCD (progressive rod-cone degeneration). These mutations typically lead to a loss of function of the PRCD protein, which is crucial for the maintenance and stability of photoreceptor cells. The exact role of the PRCD protein is not completely understood, but it is believed to be involved in the phototransduction pathway, which is essential for converting light into electrical signals in the retina.
The malfunction or absence of PRCD disrupts this pathway, leading to photoreceptor degeneration and the resultant symptoms of retinitis pigmentosa. Over time, this degeneration spreads from the peripheral retina to the central retina, causing a progressive loss of vision. - Treatment
