Short answer · Medically reviewed summary · Last updated: 2026-05-08
Arterial Tortuosity Syndrome is an ultra-rare connective tissue disorder with an estimated prevalence of less than 1 in 1,000,000 individuals worldwide. Because the condition is often underdiagnosed or misdiagnosed due to its complex clinical presentation, the true global frequency remains unknown and may be higher than currently reported literature suggests. Is Arterial Tortuosity Syndrome considered rare or common? Arterial Tortuosity Syndrome is classified as an ultra-rare disease.
1 people with Arterial Tortuosity Syndrome have shared their first-person experience on this question at DiseaseMaps.
What is the prevalence of Arterial Tortuosity Syndrome?
Prevalence of Arterial Tortuosity Syndrome: how many people are affected worldwide, differences by sex and region, with sources.
Arterial Tortuosity Syndrome is an ultra-rare connective tissue disorder with an estimated prevalence of less than 1 in 1,000,000 individuals worldwide. Because the condition is often underdiagnosed or misdiagnosed due to its complex clinical presentation, the true global frequency remains unknown and may be higher than currently reported literature suggests.
Is Arterial Tortuosity Syndrome considered rare or common?
Arterial Tortuosity Syndrome is classified as an ultra-rare disease. It is a genetic condition caused by mutations in the SLC2A10 gene, which affects the structural integrity of arterial walls. Due to its extreme rarity, clinical data is limited, and many medical professionals may never encounter a case in their entire career.
How does Arterial Tortuosity Syndrome affect different populations?
The condition shows no significant gender bias, affecting males and females with equal frequency. While Arterial Tortuosity Syndrome has been reported in various ethnic groups globally, the data is insufficient to establish specific geographic or ancestral prevalence patterns. Symptoms typically present in early childhood, often identified during pediatric cardiac evaluations or when characteristic physical features are observed.
What are the challenges in tracking prevalence?
Accurate reporting for Arterial Tortuosity Syndrome faces several hurdles:
- Diagnostic Delay: Symptoms may be mild in some individuals, leading to a lack of clinical investigation.
- Misdiagnosis: The syndrome is frequently confused with other connective tissue disorders, such as Loeys-Dietz syndrome or Marfan syndrome.
- Under-reporting: Many cases occurring in regions with limited access to advanced genetic testing may never be officially recorded in medical registries.
