Disease Details
Family Health Simplified
- Description
- Hereditary spastic paraplegia 28 (SPG28) is a neurodegenerative disorder characterized primarily by progressive weakness and stiffness (spasticity) in the muscles of the lower limbs.
- Type
- Hereditary spastic paraplegia 28 (SPG28) is typically inherited in an autosomal recessive manner.
- Signs And Symptoms
-
Hereditary Spastic Paraplegia 28 (SPG28) is a type of hereditary spastic paraplegia. It is characterized by the following signs and symptoms:
- Progressive stiffness and spasticity (muscle tightness) in the lower limbs
- Muscle weakness, particularly in the legs
- Difficulty with walking, often leading to a more pronounced gait disturbance
- Some individuals may experience urinary urgency or incontinence
- In some cases, there may also be mild cognitive impairment or other neurological signs
These symptoms typically worsen over time, leading to increased difficulty with mobility. - Prognosis
-
Hereditary Spastic Paraplegia 28 (HSP 28) is a subtype of hereditary spastic paraplegia, a group of genetic disorders characterized by progressive weakness and spasticity (stiffness) of the legs. The prognosis can vary widely among individuals.
Generally, HSP 28 leads to a gradual worsening of symptoms over time. Most individuals with HSP 28 will experience increasing difficulty with walking and mobility, but the degree of impairment can differ significantly. Some may become wheelchair-dependent, while others maintain a degree of independent ambulation.
Life expectancy for individuals with HSP 28 is typically not reduced, but quality of life may be impacted due to mobility issues and potential complications such as falls or spasticity-related pain. Management is focused on symptomatic relief, physiotherapy, assistive devices, and sometimes medications to manage spasticity. Regular follow-up with a neurologist or specialist in genetic disorders is recommended to monitor progression and adjust treatment as needed. - Onset
- Hereditary Spastic Paraplegia 28 (SPG28) typically presents with an onset in adulthood. The exact age of onset can vary, but symptoms usually appear in the third to fifth decades of life.
- Prevalence
- The prevalence of hereditary spastic paraplegia (HSP) type 28 is not well-defined due to its rarity. HSPs, in general, are a group of inherited disorders, and the specific prevalence can vary widely. However, HSP type 28 is considered very rare. If you need more precise numbers, specific genetic studies or registries might provide more detailed data.
- Epidemiology
- Hereditary Spastic Paraplegia 28 (SPG28) is a rare form of hereditary spastic paraplegia. Due to its rarity, specific epidemiological data is limited and not well-documented in the current medical literature. Generally, hereditary spastic paraplegias as a group have a prevalence of around 1-9 per 100,000 people, but precise figures for SPG28 are not available.
- Intractability
- Hereditary spastic paraplegia type 28 (HSP28) is generally considered intractable in the sense that there is currently no cure available. Treatment is typically focused on managing symptoms and improving quality of life through physical therapy, medications to manage spasticity, and assistive devices. Research is ongoing to better understand the disease and develop more effective treatments.
- Disease Severity
-
Hereditary spastic paraplegia (HSP) 28, caused by mutations in the DDHD1 gene, typically manifests as a progressive neurological disorder. The severity can vary, but it generally leads to significant spasticity and weakness in the lower extremities.

- Pathophysiology
- Hereditary spastic paraplegia 28 (HSP28) is a subtype of hereditary spastic paraplegia, a group of genetic disorders characterized by progressive weakness and spasticity of the lower extremities. The pathophysiology of HSP28 involves mutations in the DDHD1 gene, which encodes a phospholipase enzyme critical for lipid metabolism and maintaining membrane integrity. These mutations lead to dysfunctional or deficient enzyme activity, resulting in abnormal lipid accumulation in neurons. This disrupts axonal transport and causes axonal degeneration, particularly in the long corticospinal tracts, leading to the characteristic spasticity and weakness in the legs.
- Carrier Status
- Hereditary spastic paraplegia 28 (HSP28) is an autosomal dominant disorder. Carrier status typically isn't applicable because autosomal dominant disorders usually require only one copy of the mutated gene for the disease to manifest, and affected individuals typically display symptoms if they have the mutation. Therefore, individuals with one mutated gene copy are usually considered affected, rather than carriers.
- Mechanism
-
Hereditary spastic paraplegia 28 (HSP28) is a subtype of hereditary spastic paraplegia (HSP), a group of genetic neurodegenerative disorders characterized primarily by progressive spasticity and weakness of the lower extremities.
**Mechanism:**
HSP28 is caused by mutations in the gene DDHD2, which encodes the enzyme phospholipase DDHD2. This enzyme is involved in the metabolism of phospholipids, which are essential components of cell membranes.
**Molecular Mechanisms:**
- **Phospholipase Activity:** DDHD2 plays a critical role in the hydrolysis of specific phospholipids, influencing lipid composition and homeostasis.
- **Lipid Droplet Regulation:** DDHD2 is implicated in the formation and regulation of lipid droplets within cells.
- **Axonal Transport and Maintenance:** Proper function of DDHD2 is essential for maintaining the integrity of axons, particularly in motor neurons. Disruption in phospholipid metabolism can impair axonal transport and maintenance, leading to the progressive neurological symptoms observed in HSP28.
- **Neuropathology:** Mutations in DDHD2 can disrupt its enzymatic function, leading to abnormal phospholipid accumulation and consequential neurodegeneration, primarily affecting the corticospinal tracts.
These molecular disruptions ultimately result in the progressive lower limb spasticity and weakness characteristic of HSP28. - Treatment
-
There is no cure for Hereditary Spastic Paraplegia 28 (HSP28), and treatment primarily focuses on managing symptoms and improving quality of life. Common treatment approaches include:
1. **Physical Therapy:** To maintain muscle strength, flexibility, and mobility.
2. **Medications:** To manage symptoms such as spasticity, pain, and bladder control issues. Common medications may include baclofen, tizanidine, or botulinum toxin injections.
3. **Assistive Devices:** Use of canes, walkers, or wheelchairs to aid with mobility.
4. **Occupational Therapy:** To assist with daily activities and improve functional abilities.

-
Hereditary Spastic Paraplegia 28 (HSP28) is a rare genetic condition characterized by progressive muscle stiffness and weakness, primarily in the lower limbs.
1. **Compassionate Use Treatment**: Compassionate use, also known as expanded access, allows patients to gain access to investigational treatments outside of clinical trials. Eligibility and treatment options depend on the specific regulatory framework in each country.
2. **Off-label Treatments**: Off-label treatments may involve using existing medications in ways not specified in their official labeling. For HSP28, drugs aimed at alleviating spasticity and muscle stiffness, such as baclofen, tizanidine, or gabapentin, might be prescribed off-label.
3. **Experimental Treatments**: Investigational therapies currently being researched may include novel drug candidates, gene therapy approaches, or other advanced treatments. Participation in clinical trials may provide access to these experimental approaches.
Consultation with a healthcare provider specializing in genetic and neuromuscular disorders is essential for personalized treatment options. - Lifestyle Recommendations
