Disease Details
Family Health Simplified
- Description
- IFT172-related disorder is a genetic condition caused by mutations in the IFT172 gene, leading to a range of ciliopathies, which can affect multiple organ systems including the eyes, kidneys, brain, and skeleton.
- Type
- IFT172-related disorders are typically categorized as ciliopathies, which affect the cilia, hair-like structures on the surface of cells. The genetic transmission of these disorders is usually autosomal recessive.
- Signs And Symptoms
-
IFT172-related disorders are a group of conditions caused by mutations in the IFT172 gene. These disorders often fall under the broader category of ciliopathies, which are diseases related to defects in the cilia, the hair-like structures on the surface of cells. The specific signs and symptoms can vary widely depending on the particular condition, but they generally include:
- **Skeletal abnormalities:** These can include polydactyly (extra fingers or toes), limb shortening, and other bone malformations.
- **Retinal degeneration:** Progressive vision loss due to the degeneration of retinal cells.
- **Renal anomalies:** Kidney problems, including cystic kidneys.
- **Neurological issues:** These can include developmental delay, intellectual disability, and, in some cases, encephalocoele (a sac-like protrusion of the brain).
- **Respiratory problems:** Recurrent respiratory infections and chronic respiratory issues due to defects in cilia in the respiratory tract may occur.
- **Obesity:** Some individuals may also experience obesity as part of the syndrome associated with IFT172 mutations.
The symptoms can vary widely, even among individuals with the same genetic mutation. Diagnosis often involves genetic testing to confirm the presence of mutations in the IFT172 gene. - Prognosis
-
IFT172-related disorders, which involve mutations in the IFT172 gene, can result in a range of ciliopathies, such as Bardet-Biedl syndrome and Jeune asphyxiating thoracic dystrophy. The prognosis for individuals with IFT172-related disorders can vary widely depending on the specific condition and its severity. Some general aspects of the prognosis include:
1. **Bardet-Biedl Syndrome (BBS)**: This disorder often involves progressive vision loss due to retinal dystrophy, obesity, renal abnormalities, polydactyly, and developmental delays. Life expectancy can be reduced, primarily due to complications from renal disease or other systemic issues.
2. **Jeune Asphyxiating Thoracic Dystrophy (JATD)**: This condition is characterized by a narrow chest, short ribs, and respiratory insufficiency. The prognosis can be quite severe, with many affected individuals experiencing life-threatening complications during infancy or early childhood due to respiratory failure. Long-term outcomes depend on the severity of the respiratory and renal complications.
Overall, the prognosis for individuals with IFT172-related disorders is dependent on the specific manifestations and severity of the symptoms. Early diagnosis and tailored medical management can sometimes improve quality of life and health outcomes. - Onset
- IFT172-related disorder, often associated with retinal dystrophy and other ciliopathies, typically presents with symptoms from birth or during early childhood. Onset can vary significantly depending on the specific manifestation and severity of the disorder.
- Prevalence
- The prevalence of IFT172-related disorders, such as Short-Rib Thoracic Dysplasia 10 (SRTD10) and Bardet-Biedl Syndrome (BBS), is not well established due to their rarity. No substantial data or exact numbers are available to accurately define their prevalence, suggesting it is considered very rare (nan).
- Epidemiology
-
IFT172-related disorder (also known as IFT172 ciliopathy) is a rare genetic condition caused by mutations in the IFT172 gene, which is involved in intraflagellar transport. The disorder is part of a group of diseases known as ciliopathies, which affect the function of cilia, hair-like structures on cells that play crucial roles in cell signaling and fluid movement.
Epidemiologically, IFT172-related disorder is extremely rare, with only a limited number of cases reported in the medical literature. Due to its rarity, precise prevalence and incidence rates are not well-established. The disorder can manifest with a variety of symptoms, including retinal degeneration, polydactyly, skeletal abnormalities, neurodevelopmental issues, and kidney disease.
Overall, its occurrence likely varies among different populations, but it is typically diagnosed through genetic testing and clinical evaluation of the presenting symptoms. - Intractability
- IFT172-related disorders, which are linked to mutations in the IFT172 gene, are typically associated with ciliopathies affecting multiple organ systems. Treatment approaches can vary depending on the specific symptoms and severity, but these disorders are generally challenging to treat due to their genetic nature and complexity. While certain symptomatic treatments and supportive care may help manage specific aspects of the disorder, there is currently no cure, making IFT172-related disorders often considered intractable.
- Disease Severity
- IFT172-related disorders, part of a broader group known as ciliopathies, vary widely in disease severity. The severity can range from mild to severe, depending on the specific mutation and the affected individual. Some associated conditions include Bardet-Biedl syndrome and Jeune asphyxiating thoracic dystrophy, each with its own range of clinical manifestations that can affect multiple organ systems including vision, kidney function, skeletal structure, and intellectual development.
- Pathophysiology
- IFT172-related disorder is associated with mutations in the IFT172 gene, which encodes a protein integral to Intraflagellar Transport (IFT). This transport system is crucial for the assembly and maintenance of cilia, cellular organelles involved in signal transduction and fluid movement. Mutations in IFT172 disrupt ciliary function, leading to a spectrum of conditions known as ciliopathies. These can manifest in multiple organ systems, including the kidneys, eyes, and central nervous system, resulting in conditions such as polydactyly, retinal degeneration, and skeletal abnormalities.
- Carrier Status
- IFT172-related disorders are associated with mutations in the IFT172 gene. Individuals who are carriers of a single mutated copy (heterozygous) of the gene generally do not show symptoms but can pass the mutation to their offspring. If two carriers have a child, there is a 25% chance the child will inherit mutations from both parents and develop the disorder, a 50% chance the child will be a carrier like the parents, and a 25% chance the child will inherit two normal copies of the gene. Carrier screening can identify individuals who carry a single mutated copy of the IFT172 gene.
- Mechanism
-
IFT172-related disorder is linked to mutations in the IFT172 gene, which encodes a protein involved in intraflagellar transport (IFT). The IFT system is crucial for the biogenesis and maintenance of cilia, which are hair-like structures on the cell surface that play key roles in signaling pathways, cell locomotion, and sensory functions.
Molecular Mechanisms:
1. **IFT Complex Function**: IFT172 is a part of the IFT complex B, which is responsible for anterograde transport (movement from the base to the tip of the cilium) of ciliary proteins and other components essential for cilium assembly and function.
2. **Protein Transportation**: IFT172 interacts with microtubules and other IFT proteins to facilitate the movement of cargo molecules along the ciliary axoneme, the central strand of the cilium consisting of microtubules.
3. **Ciliogenesis**: Mutations in IFT172 can disrupt the proper formation and maintenance of cilia, leading to defective ciliogenesis. This impacts various signaling pathways that rely on ciliary function, including Hedgehog signaling, which is important in developmental processes.
4. **Cell Signaling Disruption**: Defective IFT due to IFT172 mutations can impair the sensory and signaling functions of cilia. This results in a wide range of clinical manifestations, particularly affecting tissues where cilia play essential roles such as in the kidneys, eyes, and brain.
Diseases and syndromes associated with IFT172 mutations often fall under the umbrella of ciliopathies and can include conditions such as Bardet-Biedl syndrome (BBS) and Jeune asphyxiating thoracic dystrophy (JATD). - Treatment
-
IFT172-related disorder is a genetic condition related to mutations in the IFT172 gene, which is involved in ciliary function. As of now, there is no specific cure for IFT172-related disorders. Treatment primarily focuses on managing symptoms and improving the quality of life for affected individuals. This often involves a multidisciplinary approach, which may include:
1. **Symptomatic Management:** Addressing specific symptoms such as vision problems, hearing loss, cognitive impairments, and kidney issues.
2. **Physical and Occupational Therapy:** To help improve motor skills and daily functioning.
3. **Regular Monitoring:** Frequent follow-up with healthcare providers to monitor disease progression and manage complications.

-
IFT172-related disorders are a group of conditions associated with mutations in the IFT172 gene, which is crucial for intraflagellar transport and ciliogenesis. These disorders often manifest with a spectrum of clinical features, including retinal dystrophy, skeletal abnormalities, and brain development issues.
Repurposable drugs for IFT172-related disorders are not well-established due to the rarity and complexity of these conditions. However, research into ciliopathies and related pathways might offer some potential therapeutic options. Drugs that target ciliary function, inflammation, or cellular stress responses could be of interest. Therapeutics such as antioxidants, anti-inflammatory agents, or modulators of ciliary signaling pathways might have potential, but their use would require thorough clinical investigation and validation.
Continuous research is key in identifying and validating any repurposable drugs for these disorders. Consulting with a healthcare provider who specializes in genetic diseases is essential for up-to-date information and treatment options. - Metabolites
-
IFT172-related disorders, such as those involving mutations in the IFT172 gene, can lead to a range of ciliopathies, which are diseases associated with dysfunctional cellular cilia. These conditions often result in clinical manifestations affecting multiple organ systems, including the brain, eyes, kidneys, and skeleton.
As of now, there is limited specific information available directly linking IFT172-related disorders with particular metabolites. Metabolites are small molecules involved in the metabolism within organisms, and profiling them (metabolomics) can sometimes help in understanding disease mechanisms or discovering potential biomarkers for diagnosis and treatment. However, specific metabolomic profiles for IFT172-related disorders are not well-documented in the current biomedical literature. Further research might be needed to identify any distinct metabolomic signatures associated with these conditions. - Nutraceuticals
-
IFT172-related disorders are linked to mutations in the IFT172 gene, which can affect ciliary function. Nutraceuticals, while not a cure, may provide supportive benefits. Antioxidants like vitamin C, vitamin E, and omega-3 fatty acids may help reduce oxidative stress, a common issue in cellular dysfunction. However, specific nutraceutical recommendations should be personalized based on individual needs and medical advice.
Nanotechnology (nan) in the context of IFT172-related disorders could provide future therapeutic options through targeted drug delivery systems and advanced diagnostic tools. Research in this area is ongoing, and while promising, it is yet to result in definitive treatments for these specific genetic disorders. - Peptides
- IFT172-related disorders are associated with mutations in the IFT172 gene, which can lead to conditions such as Bardet-Biedl syndrome and Jeune asphyxiating thoracic dystrophy. There is no specific peptide-based treatment for these disorders. Treatments are mainly supportive and symptom-specific, focusing on managing the various manifestations of the disease.
