Ohdo syndrome Maat-Kievit-Brunner type is a rare genetic condition, also known as Maat-Kievit-Brunner syndrome. It is named after Dr. Heron Maat, Dr. Henk Burggraaff Kievit, and Dr. Han Brunner, who first described the syndrome in the medical literature. Ohdo syndrome Maat-Kievit-Brunner type is a part of the catalog of rare diseases and syndromes, and it has been referenced in numerous scientific articles.

This syndrome is associated with mutations in the MED12 gene, and it follows an X-linked inheritance pattern. It affects mostly males, with a frequency of approximately 1 in 50,000 to 100,000 males. The MED12 gene is responsible for encoding a protein that plays a role in the development of various organ systems in the body.

Patients with Ohdo syndrome Maat-Kievit-Brunner type usually present with intellectual disability, delayed growth and development, distinctive facial features, hearing loss, and other additional medical issues. Although there is no specific treatment for this condition, genetic testing can be done to confirm the diagnosis. With this testing, the associated genes and gene mutations can be identified, providing more information about the condition.

Frequency

The Ohdo syndrome Maat-Kievit-Brunner type is a rare genetic condition associated with intellectual disability and distinctive facial features. It is one of the rarest forms of Ohdo syndrome, with only a few reported cases in the medical literature.

This condition follows an X-linked inheritance pattern, which means it primarily affects males. Females are typically carriers of the gene mutation but do not typically show symptoms of the syndrome.

The problem isn’t a shortage of people wanting to be doctors, but rather, too few opportunities for training. Medical schools have increased class sizes by 30% since 2002, but federal funding for residency training – an essential step in the process of becoming a practicing physician – has not increased since 1997, according to Inside Higher Ed.

The frequency of Ohdo syndrome Maat-Kievit-Brunner type is unknown, as it is such a rare condition. It is estimated to affect fewer than 1 in 1 million individuals worldwide. However, due to its rarity, the true frequency could be even lower.

Diagnosis of Ohdo syndrome Maat-Kievit-Brunner type can be confirmed through genetic testing, which can identify mutations in the gene responsible for the syndrome.

Causes

The Ohdo syndrome Maat-Kievit-Brunner type is a rare genetic condition that is inherited in an X-linked recessive manner. This means that the condition primarily affects males, who inherit the mutated gene from their mothers. Females may also be affected if they inherit two copies of the mutated gene, one from each parent.

The specific genetic causes of the Ohdo syndrome Maat-Kievit-Brunner type are not yet fully understood. However, scientific research and genetic testing have identified mutations in the MED12 gene as a possible cause of this condition. The MED12 gene provides instructions for making a protein that is involved in the regulation of gene activity.

More research and genetic testing are needed to better understand the role of the MED12 gene in the development of Ohdo syndrome Maat-Kievit-Brunner type. Additional studies on other genes and genetic factors may also provide more information about the causes of this condition.

Patients diagnosed with the Ohdo syndrome Maat-Kievit-Brunner type may benefit from further genetic testing and counseling to learn more about the specific genetic changes associated with their condition. Advocacy organizations, such as the Ohdo Syndrome Foundation and the Genetic and Rare Diseases (GARD) Information Center, can provide additional resources and support for individuals and families affected by this syndrome.

Inheritance

The Ohdo syndrome Maat-Kievit-Brunner type is a rare genetic condition with an X-linked inheritance pattern. This means that the condition is more common in males and is passed on from a mother who carries the gene to her children. Females who inherit only one copy of the affected gene are typically carriers and may not show any symptoms or have milder symptoms compared to affected males.

The condition is caused by mutations in the KAT6B gene and is also known as the Maat-Kievit-Brunner syndrome. It is named after the scientists who first described the syndrome. Additional information about the condition can be found in scientific articles and resources such as the OMIM database and PubMed.

Support and advocacy groups, as well as genetic counseling, can provide more information for patients and families affected by Ohdo syndrome Maat-Kievit-Brunner type. These organizations can provide support, education, and resources to learn more about the condition and connect with other families and individuals with similar experiences.

The frequency of Ohdo syndrome Maat-Kievit-Brunner type is not well established, but it is considered a very rare condition. It is often diagnosed based on clinical features and genetic testing of the KAT6B gene.
