Osteochondritis Dissecans (OCD) is a rare condition that affects the bones and joints. It is characterized by the detachment of a piece of cartilage and underlying bone from the joint.

Familial Osteochondritis Dissecans is a specific form of this condition that has a genetic basis. It is inherited in an autosomal dominant manner, which means that a person with the condition has a 50% chance of passing it on to each of their children. The specific gene associated with familial osteochondritis dissecans has not yet been identified, but research is ongoing to better understand the underlying genetic components of the condition.

The Online Mendelian Inheritance in Man (OMIM) catalog provides more information about the genetic component of familial osteochondritis dissecans. There are also resources available that provide support and advocacy for patients and families affected by this rare genetic condition.

Familial osteochondritis dissecans is primarily associated with the knee joints, although it can also affect other joints. The hallmark feature of this condition is the detachment of a piece of cartilage and underlying bone from the joint, which can cause joint pain, stiffness, and limited range of motion.

If you or a family member has been diagnosed with familial osteochondritis dissecans, it is recommended to consult with a genetic counselor or a healthcare professional specializing in genetic testing to learn more about the inheritance pattern and available testing options. Additional scientific articles and references can also provide further information on this rare genetic condition.

Frequency

Familial osteochondritis dissecans is a rare condition that affects the joints and bones. It is estimated to occur in about 1 in 1,000 live births.

Even with health insurance, patients in the U. S. have a hard time affording their medical care. About one in five working-age Americans with health insurance, and more than half of those without health insurance, reported having trouble paying their medical bills in the last year, according to S. News & World Report.

This condition can be sporadic, occurring without any associated family history. However, it has been reported to have familial cases as well. According to a study published on PubMed, familial osteochondritis dissecans accounted for about 15% of all cases of the condition.

The exact cause of familial osteochondritis dissecans is still unknown. However, it is believed to have a genetic component. Several genes have been identified as potential causes of the condition, including the COMP and COL11A1 genes. Inheritance is typically autosomal dominant, meaning that a mutation in one copy of the gene is enough to cause the disease.

For more information about the genetic component of familial osteochondritis dissecans, you can visit the Online Mendelian Inheritance in Man (OMIM) database. This resource provides comprehensive information about various genetic diseases, including osteochondritis dissecans.

In addition to genetic causes, other factors such as trauma and repetitive stress on the joints can contribute to the development of osteochondritis dissecans. Stiffness and additional symptoms may be present in affected individuals.

The Dahl Osteochondritis Dissecans Center is an advocacy and support center for individuals affected by this condition. They provide resources and information about osteochondritis dissecans, including genetic testing options.

Causes

Familial osteochondritis dissecans is a rare condition that affects the joints and bones. It is thought to be caused by a combination of genetic and environmental factors.

Genetic factors play a major role in the development of familial osteochondritis dissecans. It is believed that certain genes inherited from parents can increase the risk of developing this condition. However, the exact genes involved and the specific inheritance pattern are not yet fully understood.

Scientific research and genetic testing are ongoing to learn more about the underlying genetic components of familial osteochondritis dissecans. Additional information about the genetic causes of this condition can be found in scientific articles and databases like PubMed and OMIM.

In addition to genetic factors, other causes and risk factors may contribute to the development of osteochondritis dissecans. These include repetitive stress or injury to the affected joints, poor blood supply to the bones, and abnormalities in the structure of the bone and cartilage.

Although familial osteochondritis dissecans is considered rare, sporadic cases of the condition can also occur. This means that the condition may develop without a known family history of the disease.

More research is needed to fully understand the frequency and inheritance patterns of familial osteochondritis dissecans. Resources like the Online Mendelian Inheritance in Man (OMIM) database and the Catalog of Human Genes and Genetic Disorders can provide more information on this topic.

Understanding the causes and underlying mechanisms of familial osteochondritis dissecans can help in the development of better diagnostic tools, treatment options, and support systems for patients and their families.

Research has identified a gene called DALH (Decalcification of the Acquired Ligamentous Hypertrophy), which is associated with familial osteochondritis dissecans. The DALH gene plays a role in the development and maintenance of joint tissues, including cartilage and bone.

This gene is inherited in an autosomal dominant manner, which means that having a mutation in one copy of the gene is enough to cause the condition. However, in some cases, the condition may be sporadic, meaning it occurs without a family history.

To learn more about the DALH gene and its role in familial osteochondritis dissecans, several resources are available:

  • PubMed: The PubMed database contains scientific articles and studies on various topics, including genetics and osteochondritis dissecans. Searching for “Familial osteochondritis dissecans” and “DALH gene” in PubMed can provide more information about the gene and its associated condition.
  • OMIM: Online Mendelian Inheritance in Man (OMIM) is a catalog of human genes and genetic disorders. OMIM provides detailed information on the DALH gene and lists the associated familial osteochondritis dissecans as one of its features. OMIM can be a valuable resource for genetic information and references to scientific articles.
  • Genetic advocacy and support organizations: Various organizations support individuals and families affected by genetic conditions. These organizations often provide resources, information, and support for those seeking to learn more about familial osteochondritis dissecans and the DALH gene.
  • Genetic testing: Genetic testing can be performed to identify mutations in the DALH gene and determine the likelihood of developing familial osteochondritis dissecans. This testing can be done through specialized laboratories and medical professionals who specialize in genetic diseases.

By learning more about the DALH gene and its role in familial osteochondritis dissecans, individuals can better understand the underlying causes of this condition, potential inheritance patterns, and available resources and support.

Inheritance

Familial osteochondritis dissecans is a rare genetic condition that affects the bones and joints, particularly the knee. It is associated with a genetic cause, unlike the sporadic form of osteochondritis dissecans.

There are additional genes that may be involved in the inheritance of familial osteochondritis dissecans, but more research is needed to understand their specific role in the condition. The exact inheritance pattern is not well understood, but some cases appear to have an autosomal dominant pattern, meaning that a person only needs to inherit one copy of the mutated gene from one parent to develop the condition.

For patients and their families, it is important to have access to resources and information for support. The Osteochondritis Dissecans Research and Advocacy Center provides a catalog of articles and references on the genetic causes of familial osteochondritis dissecans and other related diseases. PUBMED and OMIM are also excellent scientific resources to learn more about this rare condition, its underlying genetic causes, and potential inheritance patterns.

Genetic testing can provide valuable information for families affected by familial osteochondritis dissecans. Testing can help identify the specific gene mutation responsible for the condition and allow for more informed genetic counseling.
