Short answer · Medically reviewed summary · Last updated: 2026-05-08
Arterial Tortuosity Syndrome is a rare hereditary condition caused by specific genetic mutations, meaning it is passed down through families in an autosomal recessive inheritance pattern. Because it is genetic, an individual must inherit one pathogenic variant from each parent to be affected by the disorder. Is Arterial Tortuosity Syndrome hereditary? Yes, Arterial Tortuosity Syndrome is strictly hereditary.

Is Arterial Tortuosity Syndrome hereditary?
Is Arterial Tortuosity Syndrome hereditary? The genetic component explained in plain language, reviewed against medical sources, with patient experiences.
Arterial Tortuosity Syndrome is a rare hereditary condition caused by specific genetic mutations, meaning it is passed down through families in an autosomal recessive inheritance pattern. Because it is genetic, an individual must inherit one pathogenic variant from each parent to be affected by the disorder.
Is Arterial Tortuosity Syndrome hereditary?
Yes, Arterial Tortuosity Syndrome is strictly hereditary. It follows an autosomal recessive inheritance pattern, which means that parents of an affected child are typically asymptomatic carriers, each carrying one mutated copy of the SLC2A10 gene. When both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit both mutated copies and develop the syndrome.
What is the role of genetic testing and counseling?
Genetic testing for Arterial Tortuosity Syndrome involves sequencing the SLC2A10 gene to identify pathogenic variants. Clinical geneticists recommend this testing for individuals presenting with characteristic vascular findings, such as elongation and tortuosity of the large and medium-sized arteries. Because Arterial Tortuosity Syndrome is rare, genetic counseling is essential for families to understand their recurrence risks and explore reproductive options.
Are de novo mutations common in this condition?
De novo (spontaneous) mutations are not the primary cause of Arterial Tortuosity Syndrome. Because the condition is autosomal recessive, it is inherited from parents who are carriers, rather than occurring as a new mutation in the affected individual. The following points summarize the genetic facts regarding the condition:
- Inheritance pattern: Autosomal recessive.
- Primary gene involved: SLC2A10.
- Carrier risk: If a sibling is affected, there is a 66% chance that an asymptomatic sibling is a carrier.
- Prenatal options: Genetic counseling can facilitate prenatal diagnosis or preimplantation genetic testing (PGT) for families with a known mutation.
Next steps
- Consult a clinical geneticist to confirm a diagnosis of Arterial Tortuosity Syndrome through molecular testing.
- Speak with a genetic counselor to discuss family planning and carrier testing for relatives.
