Deafness and myopia syndrome, also known as myopia-sensorineural deafness syndrome, is a rare genetic condition that affects a patient’s vision and hearing. It is described in the scientific literature and is cataloged in the Online Mendelian Inheritance in Man (OMIM) database. This syndrome is associated with a high frequency of myopia, a condition that causes nearsightedness.
Patients with deafness and myopia syndrome experience sensorineural deafness, which means that the hearing loss is caused by damage to the inner ear or the nerve pathways that transmit sound to the brain. The exact causes of this syndrome are still unknown, but research suggests that mutations in certain genes may play a role in its development.
In order to learn more about this rare condition, patients and their families can turn to advocacy organizations, such as the Deafness and Myopia Syndrome Center, for additional information and support. These organizations often provide resources, articles, and access to scientific publications through their online catalogs. Patients can also find information on genetic testing for this syndrome, which can help confirm the diagnosis.
Testing for deafness and myopia syndrome can be beneficial for patients and their families, as it can provide valuable information about the inheritance pattern and the risk of passing the condition on to future generations. Genetic testing can also help doctors determine the best course of treatment and management for patients with this syndrome.
For more information about deafness and myopia syndrome, patients and healthcare professionals can consult the OMIM database, PubMed articles, and other scientific references. These resources provide a wealth of information about the syndrome, including its symptoms, inheritance pattern, and associated genes.
Frequency
The Deafness and myopia syndrome is a rare genetic condition. According to OMIM (Online Mendelian Inheritance in Man), this syndrome has a high frequency of occurrence. It is estimated that about 1 in 60,000 individuals are affected by this syndrome. The syndrome is characterized by sensorineural hearing loss and myopia, a condition where the eyes are unable to focus properly on objects.
There are very few diseases with a higher frequency of occurrence than the Deafness and myopia syndrome. As a result, it is considered a rare condition. Due to its rarity, there are limited resources available for testing and advocacy. However, there are specialized centers and genetic testing centers that can provide support and additional information about the syndrome.
The causes of the Deafness and myopia syndrome are still being researched. Some associated genes have been described, but the exact genetic basis of the syndrome is not fully understood. The length of the genes associated with this syndrome can vary, which makes genetic testing challenging.
For more information about the frequency and genetics of the Deafness and myopia syndrome, scientific articles can be found on PubMed. The PubMed database contains a catalog of articles related to this condition. Additionally, OMIM provides a comprehensive list of genes associated with the syndrome.
In conclusion, the Deafness and myopia syndrome is a rare condition with a high inheritance frequency. It is associated with sensorineural hearing loss and myopia. Further research and genetic testing are needed to fully understand the syndrome and provide support to affected individuals.
Causes
The causes of Deafness and Myopia Syndrome (also known as the myopia-sensorineural deafness syndrome) are genetic in nature. The syndrome is caused by mutations in the OPA1 gene, which is responsible for encoding a protein involved in the maintenance of mitochondrial function.
According to information from the Online Mendelian Inheritance in Man (OMIM) database, this condition has been described in scientific articles under different names, including “deafness and myopia syndrome”, “myopia-sensorineural deafness syndrome”, and “DOA +”.
The OPA1 gene mutations associated with this syndrome result in a high frequency of vision and hearing loss, with individuals experiencing progressive myopia and sensorineural deafness. The exact mechanisms by which these mutations lead to the specific symptoms of the syndrome are not fully understood.
Currently, there are rare genetic testing options available for individuals suspected of having Deafness and Myopia Syndrome. Genetic testing can provide additional information about the specific gene mutations causing the condition, which can be useful for patient advocacy and support.

Learn more about the gene associated with Deafness and myopia syndrome
Deafness and myopia syndrome is a rare genetic condition characterized by sensorineural hearing loss and myopia (nearsightedness). The syndrome is caused by mutations in a specific gene, which plays a crucial role in the development and function of the inner ear and visual system.
Research has shown that the inheritance of Deafness and myopia syndrome is autosomal recessive, meaning that an affected individual must inherit two copies of the mutated gene – one from each parent – to develop the condition. In some cases, individuals may be carriers of the mutated gene without showing any symptoms.
Patients with Deafness and myopia syndrome typically experience high-frequency hearing loss, which affects their ability to hear sounds in the higher range. This can have a significant impact on their overall communication and daily functioning.
Myopia, or nearsightedness, is a condition characterized by difficulty seeing objects in the distance. In individuals with Deafness and myopia syndrome, the degree of myopia can vary, but it is typically more severe compared to individuals without the syndrome.
