Number of Conditions: 1

Loeys-Dietz Syndrome

Specialty: Genetics

Category: Connective Tissue and Skeletal Disorders

Sub-category: Aortic and Vascular Disorders

Symptoms:
aneurysms or dissections of the aorta; joint laxity; easy bruising; wide-spaced eyes; bifid uvula; cleft palate; arterial tortuosity

Root Cause:
Mutations in genes such as TGFBR1, TGFBR2, SMAD3, or TGFB2 affecting the transforming growth factor-beta signaling pathway.

How it's Diagnosed: videos
Clinical evaluation, imaging of the vasculature (e.g., echocardiography, CT/MRI), genetic testing.

Treatment:
Regular cardiovascular monitoring, beta-blockers or angiotensin receptor blockers to reduce aortic stress, and surgical repair of aneurysms.

Medications:
Beta-blockers (e.g., atenolol ) or ARBs (e.g., losartan ) to manage blood pressure and reduce strain on the aorta.

Prevalence: How common the health condition is within a specific population.
Estimated 1 in 100,000; exact prevalence unknown.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Family history; autosomal dominant inheritance.

Prognosis: The expected outcome or course of the condition over time.
Improved with early diagnosis and management; risks of vascular complications necessitate lifelong monitoring.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Aortic dissection, rupture of aneurysms, joint instability, and organ malformations.
