Spastic paraplegia type 8 (SPG8) is a rare genetic condition characterized by spasticity and weakness in the leg muscles. It is classified as a hereditary spastic paraplegia (HSP), which refers to a group of genetic disorders that cause progressive stiffness and loss of muscle control in the lower limbs.
SPG8 is caused by mutations in the KIAA0196 gene. These mutations disrupt the normal functioning of the gene and result in the degeneration of the nerve cells that control muscle movement. The exact frequency of SPG8 is unknown, but it is considered a rare condition.
Patients with SPG8 experience symptoms such as difficulty walking, muscle weakness, and increased muscle tone (spasticity) in the legs. The severity of these symptoms can vary among individuals, but they generally worsen over time. Additional information about SPG8 and other related diseases can be found in the OMIM catalog.
Support and advocacy resources are available for patients and families affected by SPG8. The Spastic Paraplegia Foundation is a scientific research center dedicated to finding a cure for spastic paraplegias. They provide information and support for patients and families, as well as funding research into the causes and treatment of these conditions.
Genetic testing is available for individuals suspected of having SPG8 in order to confirm the diagnosis. This testing can identify specific mutations in the KIAA0196 gene and help guide treatment decisions. More information about genetic testing and resources for support can be found in articles published on PubMed, the National Center for Biotechnology Information’s database of scientific publications.

Frequency
Spastic paraplegia type 8 (SPG8) is a rare genetic condition characterized by progressive stiffness and contraction of the muscles in the legs, known as spasticity. This condition is associated with mutations in the gene named WASHC5, located on chromosome 8.
The frequency of SPG8 is not well established, but it is considered to be a rare form of hereditary spastic paraplegia. The prevalence of hereditary spastic paraplegias is estimated to be between 1.3 and 9.6 per 100,000 individuals.
SPG8 is inherited in an autosomal dominant manner, which means that an affected individual has a 50% chance of passing the condition on to each of their children. However, not all individuals with a mutation in the WASHC5 gene will develop symptoms, and the severity of symptoms can vary among affected individuals.
Additional information about SPG8, including its symptoms, causes, inheritance patterns, and other associated genes, can be found in scientific resources such as the Online Mendelian Inheritance in Man (OMIM) database, PubMed, and the GeneReviews catalog.
Patients and their families may also find support and advocacy resources from organizations such as the Spastic Paraplegia Foundation and the Genetic and Rare Diseases Information Center. These resources provide more information about SPG8 and other types of hereditary spastic paraplegias, as well as tips for managing symptoms and improving quality of life.

Causes
Spastic paraplegia type 8 (SPG8) is a hereditary condition characterized by progressive spasticity and weakness in the lower limbs. It is one of the many types of hereditary spastic paraplegias (HSPs), which are a group of genetic disorders that primarily affect the muscles in the legs.
SPG8 is caused by mutations in the KIF1A gene. This gene provides instructions for making a protein that is involved in the transportation of various cellular materials, including vesicles and mitochondria, along nerve cells. Mutations in the KIF1A gene disrupt this transportation process, leading to the degeneration of nerve cells in the spinal cord responsible for controlling movement.
The inheritance pattern of SPG8 is autosomal dominant, which means that an affected individual has a 50% chance of passing the condition on to each of their children. However, not all individuals who inherit a mutation in the KIF1A gene will develop SPG8, and the severity of the condition can vary among affected individuals.
Currently, there is no cure for SPG8, but management strategies focus on alleviating symptoms and improving quality of life. Treatment options may include medication to help with spasticity, physical therapy to improve strength and mobility, and assistive devices to aid in mobility.
If you or a loved one has been diagnosed with SPG8, it is important to seek support and resources from advocacy groups and medical centers specializing in genetic conditions. These organizations can provide information, additional scientific articles, and access to genetic testing and counseling services.

Learn more about the gene associated with Spastic paraplegia type 8
Spastic paraplegia type 8 (SPG8) is a rare hereditary condition characterized by progressive stiffness and weakness in the leg muscles, known as spastic paraplegia. The condition is caused by mutations in the gene called KIAA0196 or WASHC5.
Scientific names: Spastic paraplegia 8, autosomal dominant; SPG8; Spastic paraplegia, autosomal dominant, Troyer type; Troyer syndrome
Associated symptoms of SPG8 include spasticity, which refers to the tightness and stiffness of muscles, particularly in the legs. This can lead to difficulty walking and an abnormal gait. The severity of symptoms can vary between individuals, even within the same family.
SPG8 is inherited in an autosomal dominant manner, meaning that a mutation in only one copy of the gene is sufficient to cause the condition. If one parent has SPG8, there is a 50% chance that their child will inherit the mutated gene.
Testing for the KIAA0196 or WASHC5 gene mutation can be done through genetic testing. This can provide additional information for both the patient and their family, allowing for accurate diagnosis and genetic counseling.
More information about Spastic paraplegia type 8, including its causes, symptoms, and frequency, can be found on websites such as OMIM (Online Mendelian Inheritance in Man) and PubMed. These resources are a valuable source of scientific articles and other information on genetic diseases.
The ZATZ Molecular Genetics Laboratory and the SPG8 Support and Advocacy Center also provide information and support for individuals and families affected by SPG8.
