arterial tortuosity syndrome

Arterial Tortuosity Syndrome (ATS) is a rare genetic disorder characterized by abnormal twists and turns of arteries, leading to cardiovascular complications.

Key Features of ATS:

• Abnormal Artery Twists: The most distinctive feature of ATS is the elongation and tortuosity of large and medium-sized arteries.
• Genetic Origin: ATS is caused by mutations in the SLC2A10 gene, which provides instructions for making a vital protein called GLUT10 [1][2].
• Connective Tissue Disorder: ATS is classified as a rare autosomal recessive connective tissue disorder [3].

Symptoms and Complications:

• Cardiovascular Issues: The abnormal twists and turns of arteries can lead to cardiovascular complications, including high blood pressure, heart failure, and stroke.
• Other Symptoms: Children with ATS may experience symptoms such as short stature, delayed puberty, and developmental delays.

Arterial tortuosity syndrome (ATS) is a rare genetic disorder characterized by abnormal twisting and turning of the blood vessels, particularly in the arteries. The signs and symptoms of ATS can vary from person to person but often include:

• Cardiovascular anomalies: Weak arteries that are prone to tearing; blockages can lead to respiratory problems, heart attacks, and cardiac failure [3].
• Respiratory problems: Acute respiratory symptoms, including shortness of breath, coughing, and wheezing, may occur due to the abnormal twisting of blood vessels in the lungs [4].
• Skeletal deformities: Kyphoscoliosis (abnormal curvature of the spine), chest deformities, and other skeletal abnormalities can be present in individuals with ATS [2].
• Skin and joint issues: Excessive skin folding, abnormally soft or stretchy skin, hypermobile or limited joints, slender fingers and toes, and overly curved spine are some of the common signs of ATS [6].
• Other symptoms: Arachnodactyly (spider-like fingers), blepharophimosis (drooping eyelids), congenital diaphragmatic hernia, keratoconus (a condition affecting the cornea), mental dysfunction, and telangiectasia (abnormal blood vessels on the skin) can also be present in individuals with ATS [5].

It's essential to note that not everyone with ATS will exhibit all of these symptoms, and the severity of the condition can vary greatly from person to person. If you suspect that you or a family member may have ATS, it is crucial to consult with a healthcare professional for proper diagnosis and treatment.

Arterial tortuosity syndrome (ATS) can be challenging to diagnose, but various diagnostic tests can help confirm the condition. Here are some of the diagnostic tests used for ATS:

• Physical examination: A thorough physical exam by a healthcare professional is essential in identifying the characteristic features of ATS, such as elongation and twisting of arteries [6].
• Echocardiogram: An echocardiogram can help visualize the heart's structure and function, which may be affected in individuals with ATS [6].
• CT or MRI imaging and angiography: These imaging tests can provide detailed images of the blood vessels, including the characteristic tortuosity seen in ATS [6].
• Transmission electron microscopy: This test can help identify abnormalities in elastic fibers, a hallmark of ATS [7].

In addition to these diagnostic tests, genetic testing may also be recommended for individuals suspected of having ATS. Genetic testing can confirm the presence of mutations in the SLC2A10 gene, which is associated with ATS [3][4].

It's worth noting that a combination of clinical features, family history, and imaging studies are often used to diagnose ATS, rather than relying on a single test result [9]. A healthcare professional will consider all relevant information when making a diagnosis.

Treatment Options for Arterial Tortuosity Syndrome

Arterial tortuosity syndrome (ATS) is a rare genetic disorder that affects the blood vessels, causing them to become abnormally twisted and elongated. While there is no cure for ATS, various treatment options are available to manage its symptoms and complications.

Medical Treatment

According to GeneReviews, medical treatment for ATS may involve the use of beta-adrenergic blockers or other medications such as angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor 1 (ATIIR1) antagonists like losartan [2]. These medications can help to reduce blood pressure, slow down the progression of aortic aneurysms, and prevent further complications.

Surgical Interventions

In some cases, surgical interventions may be necessary to repair or replace damaged blood vessels. This can include procedures such as heart surgery and pulmonary artery reconstruction (

Arterial Tortuosity Syndrome (ATS) can be challenging to diagnose due to its similarities with other conditions. A differential diagnosis approach is essential to rule out other possible causes.

Similarities with Ehlers-Danlos Syndrome (EDS): ATS shares some clinical features with EDS, particularly the hypermobile type. However, the main differentiator is the general tortuous nature of larger arteries in ATS [1]. This distinction is crucial for accurate diagnosis.

Other conditions to consider: ATS can be misdiagnosed as other conditions, such as:

• Nonsyndromic form of thoracic aortic aneurysm caused by PRKG1 mutations: This condition also presents with arterial tortuosity [5].
• Turner syndrome: Individuals with Turner syndrome may exhibit arterial tortuosity and other cardiovascular abnormalities [5].

Clinical features to consider: When suspecting ATS, clinicians should look for:

• Micrognathia, elongated face, high palate, beaked nose, sliding hernia, and ventricular hypertrophy [6].
• Family history: A family history of ATS or similar conditions can be a strong indicator [7].

Diagnostic tools: Echocardiography, physical examination, and radiological imaging (such as MRI or CT scans) are essential for confirming the diagnosis and detecting potential complications [8][9].

In conclusion, a thorough differential diagnosis is necessary to accurately diagnose Arterial Tortuosity Syndrome. Clinicians should consider the similarities with Ehlers-Danlos Syndrome, other conditions like nonsyndromic thoracic aortic aneurysm, and Turner syndrome, as well as clinical features such as micrognathia and ventricular hypertrophy.
