Disease Details
Family Health Simplified
- Description
- Salla disease is a rare autosomal recessive lysosomal storage disorder characterized by developmental delays, intellectual disability, and hypotonia due to impaired sialic acid metabolism.
- Type
- Salla disease is a type of lysosomal storage disorder. It is inherited in an autosomal recessive manner.
- Signs And Symptoms
-
Salla disease is a rare genetic disorder. The signs and symptoms often include:
- Developmental delays
- Hypotonia (low muscle tone)
- Ataxia (lack of muscle coordination)
- Seizures
- Intellectual disability
- Slow growth of the head circumference
- Coarse facial features
These symptoms typically become apparent during infancy and early childhood. - Prognosis
- Salla disease is a rare autosomal recessive lysosomal storage disorder characterized by the accumulation of free sialic acid in tissues due to defective sialic acid transport. Prognosis varies, but many individuals experience severe neurological impairment leading to developmental delays, intellectual disability, and motor deficits. Life expectancy can be reduced, with some individuals living into adulthood under comprehensive medical care. There is no cure, and treatment focuses on supportive therapies to manage symptoms and improve quality of life.
- Onset
- Salla disease, also known as sialic acid storage disease, typically presents in infancy. The onset often includes symptoms such as hypotonia (reduced muscle tone), developmental delays, and progressive neurological impairment.
- Prevalence
- Salla disease is an extremely rare genetic disorder. The exact prevalence is not well-documented but is considered to be very low, with only a few hundred cases reported worldwide, predominantly in Finland.
- Epidemiology
- Salla disease is a rare lysosomal storage disorder, primarily affecting individuals of Finnish descent. It is caused by mutations in the SLC17A5 gene, leading to impaired sialic acid metabolism. The overall incidence is extremely low, making it a very rare condition globally, with most cases reported in Finland and a few other isolated regions.
- Intractability
- Salla disease, also known as sialic acid storage disease, is considered intractable, meaning it currently has no cure and treatment options are limited. Management of the disease primarily focuses on symptomatic relief and supportive care.
- Disease Severity
- Salla disease severity can vary. It is a rare, inherited metabolic disorder characterized by a defect in the transport of free sialic acid within cells. Symptoms can range from mild to severe and may include developmental delays, hypotonia (reduced muscle tone), and ataxia (lack of muscle coordination). The severity often depends on the specific genetic mutation present and can impact the overall quality of life of affected individuals.
- Pathophysiology
- Salla disease, also known as free sialic acid storage disease, is an autosomal recessive lysosomal storage disorder. It is caused by mutations in the SLC17A5 gene, which encodes a protein involved in the transport of free sialic acid out of lysosomes. The defective transport leads to an accumulation of free sialic acid within lysosomes, disrupting normal cellular function. This accumulation primarily affects the central nervous system, leading to progressive neurological impairment, including developmental delay, hypotonia, ataxia, and intellectual disability.
- Carrier Status
-
Salla disease is an autosomal recessive disorder.
Carrier Status: If a person carries one mutated gene for Salla disease and one normal gene, they are considered a carrier. Carriers do not typically exhibit symptoms of the disease but can pass the mutated gene to their offspring.
nan: Please clarify or provide additional context for "nan" so I can address it accurately. - Mechanism
-
Salla disease is a rare autosomal recessive lysosomal storage disorder caused by mutations in the SLC17A5 gene. This gene encodes the sialin protein, which is responsible for transporting free sialic acid out of lysosomes. When sialin is defective or absent due to genetic mutations, sialic acid accumulates within lysosomes, disrupting normal cellular function.
At a molecular level, sialic acid is a crucial component of glycoproteins and glycolipids, influencing cellular interactions and stability. The accumulation of free sialic acid in lysosomes leads to a cascade of cellular dysfunctions, including impaired lysosomal trafficking, defective autophagy, and altered cellular signaling pathways. This results in progressive neurodevelopmental issues, hypotonia, ataxia, intellectual disability, and other systemic symptoms characteristic of Salla disease. - Treatment
-
Salla disease, or sialic acid storage disease (SASD), is a rare autosomal recessive disorder characterized by the accumulation of free sialic acid in tissues.
**Treatment:**
Currently, there is no definitive cure for Salla disease. Management typically focuses on supportive and symptomatic treatments, which may include:
- Physical therapy to aid mobility and improve muscle strength.

Salla disease, also known as sialic acid storage disease, is a rare genetic disorder. There is currently no cure for Salla disease, and treatment primarily focuses on managing symptoms and improving quality of life.
### Compassionate Use Treatment
Compassionate use treatment involves providing experimental drugs to patients who have serious or life-threatening conditions and have no other treatment options. Specific compassionate use treatments for Salla disease are not well-documented due to the rarity of the condition. Patients may contact medical research institutions or pharmaceutical companies conducting relevant research to inquire about access to experimental therapies under compassionate use protocols.
### Off-Label or Experimental Treatments
There are no widely accepted off-label or experimental treatments specifically for Salla disease. Research is ongoing, and potential treatments may include:
- **Substrate Reduction Therapy (SRT):** This aims to reduce the accumulation of harmful substances in cells.
- **Gene Therapy:** Though experimental, gene therapy aims to correct the genetic defect causing the disease.
- **Enzyme Replacement Therapy (ERT):** This approach could theoretically replace deficient enzymes, though it is not currently available for Salla disease.
- **Symptomatic Treatments:** These may include physical therapy, occupational therapy, and medications to manage seizures or other symptoms.
Given the rarity of Salla disease, treatment options should be discussed with specialized healthcare providers who can provide the most current and personalized medical advice. - Lifestyle Recommendations
