Distal arthrogryposis type 1, also known as DAS1, is a rare genetic condition characterized by muscle weakness and joint stiffness in the hands. It is inherited in an autosomal dominant pattern, meaning that an affected individual has a 50% chance of passing the condition on to their offspring. DAS1 is caused by mutations in the TPM2 gene, which plays a role in muscle contraction.

The frequency of DAS1 is not well known, but it is considered to be a rare condition. The Center for Genetic and Rare Diseases Information Center provides resources and support for individuals and families affected by DAS1. They offer a catalog of genetic testing resources, clinical trials, and more information on the inheritance and clinical characteristics of DAS1.

Further research is needed to understand the genetic causes and clinical manifestations of DAS1. Additional studies can be found on PubMed, OMIM, and ClinicalTrials.gov, where you can find scientific articles, genetic research, and clinical trials related to the condition. Advocacy organizations and support groups for DAS1, as well as other rare diseases, can also provide additional information and resources for patients.

In conclusion, Distal arthrogryposis type 1 is a rare genetic condition that causes muscle weakness and joint stiffness in the hands. It is associated with mutations in the TPM2 gene, and is inherited in an autosomal dominant manner. Further research and genetic testing are necessary to learn more about the causes and clinical manifestations of this condition, and support organizations can provide resources and support for affected individuals and their families.

Frequency

The frequency of Distal arthrogryposis type 1 is rare. It is associated with mutations in the TPM2 gene, which is inherited in an autosomal dominant manner.

Causes

Distal arthrogryposis type 1 is a rare genetic condition which is caused by mutations in the TPM2 gene. The frequency of these mutations in the general population is not well known, but they are believed to be rare.

Most cases of distal arthrogryposis type 1 have been associated with mutations in the TPM2 gene. However, there may be other genes that can also cause this condition. Further research is needed to learn more about the genetic causes of distal arthrogryposis type 1.

Studies suggest that distal arthrogryposis type 1 has an autosomal dominant inheritance pattern, which means that an affected individual has a 50% chance of passing the condition on to each of their children. However, in some cases, the condition may occur sporadically, without any family history.

Additional information about the genetic causes of distal arthrogryposis type 1 can be found in scientific articles and resources such as OMIM, Genetests, and PubMed. These resources provide detailed information on genetic mutations, inheritance patterns, and other related genes and diseases.

Learn more about the genes associated with Distal arthrogryposis type 1

Distal arthrogryposis type 1 (DA1) is a rare genetic condition characterized by the abnormal contraction of the hand and other limbs. The genetic cause of this condition is often associated with mutations in the TPM2 gene.

The TPM2 gene, located on chromosome 9, provides instructions for making a protein called tropomyosin beta-2. This protein is involved in the regulation of muscle contraction. Mutations in the TPM2 gene can disrupt the normal function of this protein, leading to the abnormal muscle contraction seen in individuals with DA1.

It is inherited in an autosomal dominant pattern, which means that an affected individual has a 50% chance of passing the condition on to each of their children. Genetic testing can be done to confirm a diagnosis of DA1 and identify specific mutations in the TPM2 gene.

Additional genes have also been associated with distal arthrogryposis, including MYH3, MYBPC1, and TNNI2. These genes are involved in muscle development and function. Mutations in these genes can cause similar symptoms to those seen in individuals with DA1.

For more detailed information on the genes associated with distal arthrogryposis type 1, you can consult the OMIM catalog. OMIM provides a comprehensive list of genes and genetic conditions, along with references to scientific articles and studies.

In addition to genetic information, there are resources available for patients and their families seeking support and advocacy for rare genetic diseases. ClinicalTrials.gov is a central resource for information on ongoing clinical trials related to distal arthrogryposis and other rare diseases.

Overall, the understanding of the genes and mutations associated with distal arthrogryposis type 1 is still evolving. More research and clinical studies are needed to further understand the causes and possible treatments for this rare genetic condition.

Inheritance

Distal arthrogryposis type 1 (DA1) is a rare genetic condition caused by mutations in the TPM2 gene. It is inherited in an autosomal dominant pattern, which means that a person with a mutation in one copy of the gene will have the condition.

Research studies have identified several other genes that can also cause distal arthrogryposis, but mutations in the TPM2 gene are the most common cause. Mutations in other genes, such as TNNI2, MYH3, and MYBPC1, have been associated with different types of distal arthrogryposis.

The frequency of distal arthrogryposis type 1 is not well-known, but it is considered a rare condition. According to the Genetics Home Reference, there have been about 60 reported cases of distal arthrogryposis type 1. However, this number may not accurately reflect the true frequency of the condition, as many cases may go undiagnosed or unreported.

Distal arthrogryposis type 1 is often diagnosed based on the clinical features and a family history of the condition. Genetic testing can be used to confirm the diagnosis and identify the specific gene mutation.

There are currently no specific treatments for distal arthrogryposis type 1, but supportive care and physical therapy can help manage the symptoms and improve quality of life for affected individuals. Some individuals may also benefit from hand surgery to correct hand contractures.
