Cardiac valvular dysplasia is a rare genetic condition associated with abnormalities in the central valves of the heart. It is sometimes called X-linked cardiac valvular dysplasia, as it is caused by mutations in the FLNA gene on the X chromosome. This genetic mutation affects the production of a protein called filamin-A, which helps support the structure and function of the heart’s valves. X-linked cardiac valvular dysplasia has been found to be more common in males than females due to its X-linked inheritance pattern.

Patients with X-linked cardiac valvular dysplasia may experience a range of symptoms, including heart murmurs, shortness of breath, and chest pain. The frequency and severity of these symptoms can vary widely between individuals. In some cases, the condition may be detected incidentally during a routine medical examination or echocardiogram.

Further research into the causes, diagnosis, and treatment of X-linked cardiac valvular dysplasia is ongoing. Genetic testing and counseling can help to identify the specific mutation causing the condition and provide information about inheritance patterns and recurrence risks for affected families. Close monitoring and regular follow-up with a cardiologist are important for managing the cardiac symptoms associated with this condition.

For more information about X-linked cardiac valvular dysplasia and support resources for patients and families, the Genetics Home Reference and OMIM databases are valuable resources. These databases provide detailed scientific articles, patient advocacy information, and references to further learn about the condition. PubMed and the Online Mendelian Inheritance in Man (OMIM) catalog can also provide additional articles and references on this rare genetic disease.

Frequency

The frequency of X-linked cardiac valvular dysplasia is currently unknown due to its rarity and the limited number of reported cases. The condition is considered to be a rare genetic disorder that affects the valves of the heart.

X-linked cardiac valvular dysplasia is caused by mutations in the FLNA gene, which is located on the X chromosome. This gene provides instructions for making a protein called filamin A, which is involved in the organization of the cell’s internal structure and helps maintain the integrity of the extracellular network.

Major health insurance companies have faced legal trouble over their claim denial practices. In February 2018, the insurance commissioner of California announced plans to investigate Aetna’s coverage denial practices after a former medical director of the insurance company admitted that he never once looked at a patient’s medical records when deciding whether to deny claims over the three years he worked in the position, according to CNN.

There are currently no specific statistics or catalogs that provide information on the frequency of X-linked cardiac valvular dysplasia. However, through advocacy and patient support groups, more cases are being identified and reported, which helps us learn more about the condition and its inheritance patterns.

Most cases of X-linked cardiac valvular dysplasia are inherited in an X-linked recessive manner. This means that the condition primarily affects males, who have one copy of the mutated FLNA gene on their X chromosome. Females are typically carriers of the condition and have one normal copy and one mutated copy of the gene.

There are also other genetic causes of cardiac valvular dysplasia, including mutations in other genes that are not associated with the X chromosome. Some of these genes include the ACTA2, SMAD3, and NOTCH1 genes.

The frequency of myxomatous dystrophy of the valves, which is more common, is reported to be around 2-3% in the general population. This condition is characterized by the degeneration of the valves and the presence of abnormal connective tissue within the valves.

Further scientific research and genetic studies are needed to better understand the frequency and genetic causes of X-linked cardiac valvular dysplasia. Additional resources and information can be found through scientific articles, patient advocacy groups, and databases such as OMIM (Online Mendelian Inheritance in Man).

Causes

X-linked cardiac valvular dysplasia is a rare genetic condition that affects the development of the cardiac valves, specifically the mitral and aortic valves. It is caused by mutations in the FLNA gene, which provides instructions for making the protein filamin-A. Mutations in this gene disrupt the normal functioning of filamin-A, leading to abnormalities in the formation and function of the cardiac valves.

The FLNA gene is located on the X chromosome, and as a result, the condition is inherited in an X-linked recessive manner. This means that the condition primarily affects males, who have one X chromosome, while females may be carriers of the mutated gene but are typically asymptomatic.

The frequency of X-linked cardiac valvular dysplasia is currently unknown. There are only a few reported cases in the medical literature, and further research is needed to determine the exact prevalence of the condition.

There are also other genetic causes of cardiac valvular dysplasia, including mutations in other genes associated with myxomatous dystrophy and other cardiovascular diseases. Some of these genes include HTN1, HTN2, SKI, COL1A2, and TGFBR2. Each gene is associated with a specific type of valvular dysplasia and can be inherited in a different manner.

Inheritance

X-linked cardiac valvular dysplasia is a rare genetic condition that is associated with mutations in the FLNA gene, which codes for the protein filamin A. This condition causes abnormalities in the development and function of the heart valves, leading to myxomatous valve dystrophy.

The FLNA gene is located on the X chromosome, which means that this condition is inherited in an X-linked recessive manner. This means that the gene mutation is located on the X chromosome, and males who inherit the mutation are more likely to show symptoms of the condition than females.

Because males have only one X chromosome, if they inherit the mutation from their mother, they will develop the condition. Females, on the other hand, have two X chromosomes, so they have a higher chance of being carriers of the mutation rather than showing symptoms. However, in some rare cases, females with two copies of the mutated FLNA gene can also develop symptoms of the condition.

The inheritance pattern of X-linked cardiac valvular dysplasia can be better understood through a pedigree analysis. In families affected by the condition, males will often show the symptoms, while females may only carry the mutated gene without showing symptoms themselves.

To learn more about the inheritance of X-linked cardiac valvular dysplasia, there are several resources available. The Online Mendelian Inheritance in Man (OMIM) database provides detailed information about the genetic causes and inheritance patterns of various genetic diseases. The Genetic and Rare Diseases Information Center (GARD) offers support and resources for patients and families affected by rare diseases.

Scientific articles published in PubMed also provide further information about the genetic causes and inheritance patterns of X-linked cardiac valvular dysplasia. These articles can be searched using keywords such as “X-linked cardiac valvular dysplasia,” “FLNA gene,” and “myxomatous valve dystrophy.”

Overall, understanding the inheritance of X-linked cardiac valvular dysplasia can help support the diagnosis and treatment of affected individuals and provide important information for genetic counseling.
