congenital heart defects, multiple types, 2

Congenital heart defects, multiple types, 2 is a condition affecting the structure and function of the heart present from birth. This condition results from a mutation in the TAB2 gene, which plays an important role in heart development. It is inherited in an autosomal dominant pattern, meaning that a single altered copy of the gene can lead to the heart malformation. Precise birth prevalence data is not available, and clinical presentation may vary between individuals.

Individuals with this condition commonly exhibit characteristic cardiac features. Aortic regurgitation is always present, while other features such as atrial fibrillation, congestive heart failure, subvalvular aortic stenosis, aortic aneurysm, left ventricular outflow tract obstruction, and a bicuspid aortic valve are observed in a subset of patients. These symptoms may be identified during evaluations for cardiac issues or incidentally found during routine examinations. Not all individuals experience every feature, and severity and specific symptoms can vary considerably.

The condition is caused by a mutation in the TAB2 gene, which is essential for proper heart formation. It is inherited in an autosomal dominant pattern, meaning that having just one copy of the altered gene can lead to the condition. While many individuals who inherit the mutation show signs of heart malformation, there is variability in the specific features and their severity. Families are encouraged to seek genetic counseling to better understand the implications for family members.

Currently, management focuses on supportive care and symptom management tailored to the individual’s needs. Treatment typically involves a multidisciplinary team that may include cardiologists and other specialists, with decisions based on the specific cardiac features present. Regular surveillance, such as periodic cardiac evaluations, is an important aspect of long-term care to help identify complications early. Patients should discuss treatment options with their healthcare team and consider genetic counseling to help navigate family planning and care decisions.

The outlook for individuals with this condition varies based on the type and severity of the heart abnormalities present. With current standards of care, many individuals are able to manage their symptoms effectively and maintain a good quality of life. Outcomes continue to evolve as advances in treatment and cardiac care improve long-term management. Because severity and disease progression can differ significantly between individuals, it is important to maintain regular follow-up with a healthcare team, and families often find it helpful to connect with specialists familiar with congenital heart conditions and genetic counseling services.

There are clinical trials currently underway exploring new treatment approaches for this condition. Patients and families interested in emerging therapies are encouraged to review available clinical trial information on ClinicalTrials.gov or to consult with their care team regarding eligibility.
