Platyspondylic lethal skeletal dysplasia Torrance type is a rare genetic condition that affects skeletal development. It is characterized by abnormal bone growth and underdevelopment of the spine, leading to a flattened appearance of the vertebrae. This condition is lethal, meaning that affected individuals are often stillborn or die shortly after birth.
Platyspondylic lethal skeletal dysplasia Torrance type is associated with mutations in the COL2A1 gene, which provides instructions for making a protein called type II collagen. Type II collagen is an important component of connective tissues, including the cartilage that makes up the skeleton. Mutations in the COL2A1 gene can disrupt the production or structure of type II collagen, leading to the skeletal abnormalities seen in this condition.
Although Platyspondylic lethal skeletal dysplasia Torrance type is considered a rare condition, more than 30 cases have been reported in scientific articles. Additional information on this condition can be found in the OMIM catalog, which provides a comprehensive database of genetic diseases.
Diagnosis of Platyspondylic lethal skeletal dysplasia Torrance type can be challenging, as the condition shares similarities with other skeletal dysplasias. Genetic testing can help confirm a diagnosis by identifying mutations in the COL2A1 gene. The frequency of these mutations in the general population is not well established.
Support and advocacy resources are available for patients and families affected by Platyspondylic lethal skeletal dysplasia Torrance type. These resources provide information on inheritance patterns, connect individuals with other affected families, and offer support for managing the challenges associated with this condition.
In conclusion, Platyspondylic lethal skeletal dysplasia Torrance type is a rare genetic condition characterized by abnormal bone growth and underdevelopment of the spine. It is associated with mutations in the COL2A1 gene, which affect the production of type II collagen. Diagnosis can be confirmed through genetic testing, and support resources are available for individuals and families affected by this condition.

Causes
Platyspondylic lethal skeletal dysplasia Torrance type is a rare genetic condition that affects the skeletal tissues. It is associated with a genetic mutation and is inherited in an autosomal recessive manner, which means that both parents must carry the mutated gene for their child to be born with the condition.
Platyspondylic lethal skeletal dysplasia Torrance type is often lethal, with affected individuals typically dying before or shortly after birth. The exact cause of the condition is not fully understood, but it is believed to be due to abnormalities in the production or structure of collagen, which is an essential protein for the formation of connective tissues.
Scientific research on this condition is limited, and there are very few documented cases. The condition was first described in 1971 by Spranger et al., and additional cases have been reported in the medical literature since then. The condition is also cataloged in the Online Mendelian Inheritance in Man (OMIM) database under the name “Platyspondylic lethal skeletal dysplasia Torrance type” (OMIM #151210).
For families affected by this rare condition, there are advocacy and support resources available. Genetic testing can be used to confirm a diagnosis, and genetic counseling can provide more information about the inheritance pattern and recurrence risk. The frequency of the condition is currently unknown.
More research is needed to fully understand the genetics and molecular mechanisms underlying this rare skeletal dysplasia. Access to scientific articles and PubMed resources can provide further information for researchers and healthcare professionals. Patient advocacy groups and support organizations can also provide resources and references for individuals and families affected by the condition.
Learn more about the gene associated with Platyspondylic lethal skeletal dysplasia Torrance type
Platyspondylic lethal skeletal dysplasia Torrance type (PLSD-T) is a very rare genetic condition that affects the growth and development of bones. It is characterized by abnormally small, flattened vertebral bodies (platyspondyly), which can result in severe skeletal abnormalities and often leads to prenatal or early childhood death. The condition is inherited in an autosomal recessive manner, meaning an affected individual must inherit two copies of the gene mutation – one from each parent – to develop the condition.
Research on PLSD-T has identified mutations in the gene associated with this condition. This gene, still known by its official name, is responsible for encoding a protein called collagen, which is essential for the normal growth and development of connective tissues in the body. Collagen provides strength and support to various tissues, including bones, cartilage, ligaments, and tendons.
Additional support for the involvement of this gene in PLSD-T comes from studies that have found mutations in other genes that also encode collagen molecules in patients with similar skeletal dysplasias. These findings further confirm the role of collagen in the development and maintenance of skeletal tissues.
To learn more about the mutation associated with PLSD-T, scientific articles and resources can be found on websites such as PubMed, OMIM (Online Mendelian Inheritance in Man), and scientific journals related to skeletal dysplasias. These resources provide detailed information on the specific gene mutations, their frequencies, and the clinical features of PLSD-T.
Advocacy organizations and support groups for rare skeletal dysplasias may also have information on PLSD-T and the specific gene mutations involved. These organizations can provide resources and connect individuals and families affected by PLSD-T with support and information about this condition.
Inheritance
Platyspondylic lethal skeletal dysplasia Torrance type, also known as Torrance-Luton type, is a rare genetic condition. It is inherited in an autosomal recessive manner, which means that both parents must carry a copy of the mutated gene for their child to be affected. The condition has been linked to mutations in the gene COL2A1, which provides instructions for making a protein called collagen type II alpha 1 chain. Collagen is an important protein found in connective tissues throughout the body, including the bones and cartilage.
There are very few reported cases of Torrance-Luton type, and scientific information about the condition is limited. More research is needed to learn about the exact causes and underlying mechanisms of this condition. However, it is believed that the mutations in the COL2A1 gene lead to abnormal collagen molecules, which result in the skeletal abnormalities observed in affected individuals.
Due to the rarity of this condition, there are limited resources available for patients and their families. However, there are advocacy and support groups, such as the Torrance-Luton Support Center and the Neumann Center for Children’s Advocacy, that provide additional information and support. These organizations can help connect individuals with resources, provide information about genetic testing, and offer support to affected individuals and their families.
For more information on Platyspondylic lethal skeletal dysplasia Torrance type, additional scientific articles can be found in the OMIM catalog and PubMed. These references contain more in-depth information about the condition, its inheritance, and associated genes. It is important to consult with a healthcare professional or a genetic counselor for accurate diagnosis, testing, and management of this rare genetic condition.
