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.

Once you do get to see the doctor, don’t be surprised if you’re rushed out of the exam room before you get all of your questions answered, according to healthcare staffing agency Staff Care. Studies show that 41% of ophthalmologists spend just 9 to 12 minutes with a patient, and 13- to 16-minute appointments are the norm for 40% of cardiologists, 37% of pediatricians, 35% of urologists, 35% of family physicians, 34% of obstetricians and gynecologists and 30% of otolaryngologists.

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.
