Some individuals with JS10 may experience developmental delays, intellectual disabilities, and motor coordination problems. Other possible complications include kidney issues, liver disease, and retinal dystrophy. Life expectancy may be affected if significant organ involvement occurs. Early intervention with therapies and regular medical monitoring can help manage symptoms and improve the quality of life. Each case is unique, and ongoing medical care is essential for the best possible outcome. - Onset
- Joubert syndrome 10 (JBTS10) typically has an onset in infancy.
- Prevalence
- The prevalence of Joubert Syndrome 10 is not well defined due to its rarity, but Joubert Syndrome overall is estimated to occur in approximately 1 in 80,000 to 100,000 live births. Specific data for the subtype associated with Joubert Syndrome 10 (caused by mutations in the CEP290 gene) are not widely available.
- Epidemiology
- Joubert syndrome 10 is a subtype of Joubert syndrome, a rare genetic disorder. The exact prevalence of this subtype isn't well-documented, given the rarity and genetic variability of Joubert syndrome overall. Generally, Joubert syndrome affects approximately 1 in 80,000 to 100,000 live births worldwide. It manifests with a specific malformation in the brain called the molar tooth sign, along with a range of neurological symptoms. Specific data on the incidence of Joubert syndrome 10 is limited due to the broad categorization of the syndrome and its many genetic subtypes.
- Intractability
- Joubert syndrome 10 (JBTS10) is a rare genetic disorder and a subtype of Joubert syndrome, which is characterized by developmental delays, ataxia, and distinctive brain abnormalities visible on MRI. The term "intractable" typically refers to conditions that are difficult to manage or control with standard treatments. Given the genetic and neurological nature of Joubert syndrome, there are currently no cures, and treatment focuses on managing symptoms and supportive care. Thus, while the disease itself cannot be cured, various interventions can help improve quality of life, but the condition can be considered intractable due to the lack of curative treatments.
- Disease Severity
- Joubert syndrome 10 is a rare genetic disorder that primarily affects the cerebellum, leading to a range of neurological symptoms. The severity of the disease can vary widely among individuals, with some experiencing mild motor and cognitive impairments, while others may have significant developmental delays and physical disabilities.

- Pathophysiology
- Joubert syndrome 10 is a subtype of Joubert syndrome, a rare genetic disorder that affects brain development, particularly the cerebellum, which is the part of the brain that coordinates movement. The pathophysiology of Joubert syndrome 10 involves mutations in the CEP104 gene, which is important for the normal development and function of cilia. Cilia are hair-like structures present on the surface of many types of cells and are essential for signaling pathways that govern brain development and function. Disruption in cilia function due to CEP104 mutations leads to the distinctive malformation of the brainstem and cerebellum, contributing to the symptoms of the syndrome, such as motor deficits, developmental delays, and abnormal eye movements.
- Carrier Status
- Joubert Syndrome 10 is inherited in an autosomal recessive manner. This means that an individual must inherit two copies of the faulty gene, one from each parent, to be affected by the condition. Carriers have only one copy of the mutated gene and typically do not show symptoms of the disease. For Joubert Syndrome 10, a carrier status indicates that the individual has one normal copy of the gene and one mutated copy.
- Mechanism
-
Joubert syndrome 10 (JBTS10) is a neurodevelopmental disorder characterized by abnormal brain structure and function, often leading to motor and cognitive impairments. The molecular mechanism underlying JBTS10 involves mutations in the OFD1 gene. This gene encodes a protein critical for the function of primary cilia, which are small, hair-like structures on the surface of cells that play a crucial role in signaling pathways during brain development.
Mutations in OFD1 disrupt the formation or function of primary cilia, impairing critical signaling pathways such as the Sonic Hedgehog (Shh) pathway, which is essential for proper brain morphogenesis. The defects in ciliary function lead to the characteristic malformations observed in the midbrain-hindbrain region, specifically the "molar tooth sign" seen on brain imaging in affected individuals. Other signaling pathways impacted by defective cilia may also contribute to the diverse clinical features of Joubert syndrome. - Treatment
