Arterial tortuosity syndrome (ATS)
Arterial tortuosity syndrome has an autosomal recessive pattern of inheritance
SymptomsCongenital diaphragmatic hernia[1]
CausesMutations in SLC2A10 gene[2][3]
Diagnostic methodCT scan, MRI [4]
TreatmentPossible surgery for aortic aneurysms[5]

Arterial tortuosity syndrome is a rare congenital connective tissue condition disorder characterized by elongation and generalized tortuosity of the major arteries including the aorta.[1][6] It is associated with hyperextensible skin and hypermobility of joints, however symptoms vary depending on the person. Because ATS is so rare, not much is known about the disease.[medical citation needed]

Signs and symptoms

7-month-old female with poor weight gain and suspected cardiac disease was diagnosed with ATS. Surface-rendered 3-D reconstruction (a and b) of the same baby illustrates excessive skin laxity leading to multiple redundant skin folds.

Among the signs and symptoms demonstrated, by this condition are the following:[1][5]

Arterial tortuosity syndrome exhibits autosomal recessive inheritance, and the responsible gene is located at chromosome 20q13.[6][2] The gene associated with arterial tortuosity syndrome is SLC2A10 and has no less than 23 mutations in those individuals found to have the aforementioned condition.[2][3]


The mechanism of this condition is apparently controlled by(or due to) the SLC2A10 gene.[4] The molecular genetic pathogenesis finds that SLC2A10 encodes GLUT10(in nuclear membrane, or the endoplasmic reticulum, the later of which GLUT10 transports DHA into).Clinically speaking, according to one review, the condition of tortuosity is seen more with the advance of age.[4][7]


In terms of the diagnosis of arterial tortuosity syndrome can be done via genetic testing,[8] as well as the following listed below:[4]


The treatment of arterial tortuosity syndrome entails possible surgery for aortic aneurysms, as well as, follow ups which should consist of EGC. The prognosis of this condition has it at about 12% mortality[5][9]
