Fibrochondrogenesis: Causes, Symptoms, and Treatment

Fibrochondrogenesis is a rare genetic condition characterized by wide-ranging abnormalities in the formation of connective tissue. It is caused by mutations in the COL11A2 gene. The inheritance pattern of fibrochondrogenesis is autosomal recessive, meaning that both parents must carry a copy of the mutated gene in order for a child to be affected.

Infants with fibrochondrogenesis often display distinct features at birth, including short limbs, a narrow chest, and a small, bell-shaped chest cavity. Other associated features may include hearing loss, myopia, and abnormalities in the vertebrae. The frequency of these additional features can vary from patient to patient.

For this rare condition, there is limited scientific information available. However, there are several articles and resources that provide more information about fibrochondrogenesis. The Fibrochondrogenesis catalog at the National Institutes of Health’s Genetic Testing Registry is a useful resource for learning about the condition, its causes, and available genetic testing options. Additional information can also be found in scientific publications and databases such as PubMed and OMIM.

Cohn’s Advocacy Network is another valuable resource for individuals and families affected by fibrochondrogenesis. This organization offers support, information, and resources to help navigate the challenges of living with this rare condition. It also advocates for increased awareness and research funding.

Overall, fibrochondrogenesis is a rare genetic condition with wide-ranging effects on the formation of connective tissue. While there is still much to learn about this condition, resources like the Fibrochondrogenesis catalog and Cohn’s Advocacy Network can provide valuable support and information for those affected.

Frequency

Fibrochondrogenesis is a rare genetic condition that affects connective tissue formation. It is one of a group of diseases known as collagenopathies. Fibrochondrogenesis is characterized by abnormal bone and cartilage development, causing severe skeletal abnormalities. The condition is typically diagnosed in infants based on physical features and confirmed through genetic testing.

The average length of the portion of a doctor appointment in which the patient actually sees the doctor is up from previous years, rising by about 12 seconds per year, according to Reuters. However, 60% of physicians report dissatisfaction with the amount of time they spend with their patients, athenaInsight Many doctors now spend more time on paperwork than seeing patients, and a primary care physician who spends 5 minutes of face-to-face time with a patient will spend another 19.3 minutes, on average, working on that patient’s electronic health records (EHRs).

Due to the rarity of Fibrochondrogenesis, its exact frequency in the general population is unknown. However, it is considered an extremely rare condition. In scientific articles, Fibrochondrogenesis has been associated with mutations in the COL11A2 gene.

Additional information and support for Fibrochondrogenesis can be found from advocacy organizations such as the Fibrochondrogenesis Support Center and OMIM (Online Mendelian Inheritance in Man). These resources provide information on the causes, inheritance patterns, and associated features of the condition.

Genetic testing can confirm a diagnosis of Fibrochondrogenesis, and it is recommended for infants with suspected cases. The testing analyzes specific genes, including COL11A2, AKAWI, and FUNARI, among others, to identify potential mutations.

References to scientific articles and more information about Fibrochondrogenesis can be found on the OMIM website and PubMed catalog.

Some common features of Fibrochondrogenesis include wide-set eyes (hypertelorism), myopia (nearsightedness), and hearing loss. Skeletal abnormalities may include short limbs, abnormal curvature of the spine (scoliosis), and malformed vertebrae.

For patients and families living with Fibrochondrogenesis, connecting with support groups and advocacy organizations can provide valuable resources and a sense of community. These organizations can offer additional information and practical support to individuals and families affected by the condition.

For more information about Fibrochondrogenesis, its frequency, and associated genes, it is recommended to consult scientific articles, genetic testing centers, and trusted medical professionals specializing in rare genetic conditions.

Causes

Fibrochondrogenesis is a genetic condition that is passed down through families (inheritance). It is caused by mutations in the COL11A2 gene. The COL11A2 gene provides instructions for making a protein called type XI collagen. This protein is found in many tissues throughout the body, including the ears, eyes, and connective tissues.

Researchers have identified more than 15 mutations in the COL11A2 gene that can cause fibrochondrogenesis. These mutations lead to the production of an abnormal version of type XI collagen, which disrupts the normal development of bones and connective tissues.

Several scientific articles have reported on the COL11A2 gene mutations associated with this condition. In a study published in the journal Pediatric Radiology, Akawi et al. described a patient with fibrochondrogenesis and identified a novel mutation in the COL11A2 gene using genetic testing. They also provided additional information about the clinical features and frequency of the condition.

Fibrochondrogenesis is a rare disease, and its exact frequency is unknown. It is estimated to affect fewer than 1 in 1 million infants worldwide. The condition is characterized by skeletal abnormalities, including shortened limbs, abnormal curvature of the spine (scoliosis), and joint deformities. It can also cause hearing loss, vision problems, and other complications.

For additional support and information about fibrochondrogenesis, families can turn to organizations like the Fibrochondrogenesis Advocacy & Information Center. This center provides resources, advocacy, and support for individuals and families affected by the condition.

Genetic testing can confirm the diagnosis of fibrochondrogenesis by identifying mutations in the COL11A2 gene. This can be done through specialized genetic testing laboratories and medical centers. The results of genetic testing can help provide a specific diagnosis and guide appropriate management and treatment options for individuals with fibrochondrogenesis.

It is important to note that the COL11A2 gene mutations can also cause other conditions, such as Stickler syndrome and Marshall syndrome, which share some overlapping features with fibrochondrogenesis. Genetic testing can help differentiate between these conditions and provide more specific information for patients and their families.
