Disease Details
Family Health Simplified
- Description
- Short-rib thoracic dysplasia 14 with polydactyly (SRTD14) is a rare genetic disorder characterized by skeletal abnormalities including a narrow chest, shortened ribs, and extra fingers or toes (polydactyly), often leading to respiratory issues and other complications.
- Type
- Short-rib thoracic dysplasia 14 with polydactyly is inherited in an autosomal recessive manner.
- Signs And Symptoms
-
Signs and symptoms of short-rib thoracic dysplasia 14 with polydactyly (SRTD14) include:
1. **Shortened ribs** - This can lead to a small chest cavity and potentially respiratory issues.
2. **Thoracic dysplasia** - Abnormal development of the thorax (chest area).
3. **Polydactyly** - Presence of extra fingers or toes.
4. **Bow-legged or knock-kneed posture** - Resulting from skeletal abnormalities.
5. **Short stature** - Height significantly below average for age and sex.
6. **Hypoplastic lungs** - Underdeveloped lungs, leading to breathing difficulties.
7. **Other potential skeletal anomalies** - Such as shortened long bones or abnormalities in the pelvis.
This condition is usually apparent at birth or early childhood due to its skeletal characteristics and may require medical intervention for respiratory and orthopedic complications. - Prognosis
-
Short-Rib Thoracic Dysplasia 14 with Polydactyly (SRTD14) is a rare genetic condition characterized by skeletal abnormalities, particularly affecting the ribs and limbs. The prognosis for individuals with SRTD14 varies widely and is largely dependent on the severity of the skeletal abnormalities and any associated complications.
Prognosis is generally poor for severe cases due to respiratory complications arising from the small, constricted chest cavity, which can lead to inadequate lung development and function. These respiratory issues often result in significant morbidity and can be life-threatening, especially in infancy.
Individuals with milder forms of the condition may survive into childhood or later, but they commonly experience a range of complications, including chronic respiratory issues, short stature, and orthopedic problems. Early diagnosis and supportive care, including respiratory support and possibly surgical interventions, can improve outcomes for some patients.
Overall, the prognosis necessitates a multidisciplinary approach for management and supportive care to address the various complications associated with the syndrome. - Onset
- Short-rib thoracic dysplasia 14 with polydactyly typically has a prenatal onset, meaning symptoms can be evident before birth.
- Prevalence
- The prevalence of Short-rib thoracic dysplasia 14 with polydactyly (SRTD14) is not precisely known, but it is considered to be a very rare genetic disorder. Due to its rarity, comprehensive prevalence data are not available.
- Epidemiology
- Short-rib thoracic dysplasia 14 with polydactyly (SRTD14) is an extremely rare genetic disorder. The precise prevalence is not well-documented due to its rarity. The condition is typically inherited in an autosomal recessive manner, meaning that two copies of the mutated gene, one from each parent, are required for an individual to be affected. The disorder is characterized by abnormal development of the bones and other tissues, leading to short ribs, a narrow thoracic cavity, and polydactyly (extra fingers or toes), among other symptoms. Cases are most often identified through genetic testing and clinical assessment of the distinct skeletal anomalies.
- Intractability
- Yes, short-rib thoracic dysplasia 14 with polydactyly (SRTD14) is generally considered intractable. This rare genetic disorder often involves severe skeletal abnormalities, including short ribs and thoracic constriction, leading to significant respiratory issues. The condition is typically inherited in an autosomal recessive pattern and can be life-threatening. Management is usually supportive and symptomatic, focusing on respiratory care and other complications, as there are no definitive cures at this time.
- Disease Severity
- Short-rib thoracic dysplasia 14 with polydactyly (SRTD14) is a severe skeletal disorder. It is characterized by short ribs, a narrow thorax, and additional digits (polydactyly), leading to respiratory distress and other systemic complications. The condition is often life-threatening in the neonatal period due to respiratory insufficiency, though the severity can vary.

- Pathophysiology
- Short-rib thoracic dysplasia 14 with polydactyly (SRTD14) is an autosomal recessive ciliopathy caused by mutations in the IFT43 gene. The pathophysiology involves defects in the function and structure of primary cilia, which are essential for various cellular signaling pathways. The disruption of these ciliary functions affects skeletal development, leading to skeletal abnormalities, including short ribs, narrow thorax, and polydactyly (extra fingers or toes). This also interferes with organ development and function, contributing to a range of clinical features associated with the disorder.
- Carrier Status
- Short-rib thoracic dysplasia 14 with polydactyly is inherited in an autosomal recessive manner. Carrier status refers to individuals who have one copy of the mutated gene but do not show symptoms of the disease. Typically, carriers of this condition are asymptomatic and unaware of their carrier status unless they undergo genetic testing or have a family history prompting investigation.
- Mechanism
-
Short-rib thoracic dysplasia 14 with polydactyly (SRTD14) is a genetic disorder that primarily affects the development of skeletal structures. The molecular mechanism involves mutations in the gene IFT43, which plays a critical role in the intraflagellar transport (IFT) process.
IFT is essential for the proper functioning of primary cilia, which are small hair-like structures on the surface of cells that play crucial roles in signaling pathways during embryonic development. Mutations in IFT43 disrupt the movement of proteins along the cilia, leading to defective ciliary function. This disruption impacts the regulation of key developmental processes, resulting in the characteristic skeletal anomalies and polydactyly (extra fingers or toes) seen in SRTD14. - Treatment
-
Short-rib thoracic dysplasia 14 with polydactyly (SRTD14) is a rare genetic disorder. Currently, there is no specific treatment for the underlying genetic cause. Management primarily focuses on supportive care and addressing symptoms:
1. **Respiratory Support**: Due to thoracic constriction, patients may require respiratory support, such as ventilators or supplemental oxygen.
2. **Surgical Interventions**: In cases of severe skeletal abnormalities or polydactyly, surgical correction may be considered.
3. **Physical Therapy**: To improve mobility and manage musculoskeletal issues.
4. **Nutritional Support**: Ensuring proper nutrition to support growth and development.
5. **Multidisciplinary Care**: Coordination among specialists (genetics, orthopedics, pulmonology) is essential for comprehensive management.
Thus, the primary goal is to improve quality of life and manage complications as they arise. - Compassionate Use Treatment
-
Short-rib thoracic dysplasia 14 with polydactyly (SRTD14) is a rare genetic disorder, and specific treatments for it are limited. Currently, there are no established compassionate use treatments or off-label therapies specifically for SRTD14. Management primarily focuses on symptomatic relief and supportive care.
In terms of experimental treatments, research and clinical trials for skeletal dysplasias and related genetic conditions may occasionally offer experimental options, but these are generally not specific to SRTD14. Participation in clinical trials investigating broader treatments for skeletal dysplasias might be considered, depending on eligibility criteria.
Supportive care can involve multidisciplinary approaches, including respiratory support, orthopedic interventions, and genetic counseling. Always consult with healthcare professionals to explore potential options, including emerging therapies that might be in the research pipeline. - Lifestyle Recommendations
