SLC2A10 and Andersen-Tawil syndrome: Since standardized diagnostic criteria for ATS are not clearly defined, the diagnostic process generally starts with clinical suspicion, which is supported by imaging modalities such as X-rays, echocardiography, CT angiography (CTA), or magnetic resonance angiography (MRA), and is ultimately confirmed through genetic testing for SLC2A10 mutations [5]. Imaging plays an essential role in the diagnosis of ATS, with several characteristic signs that might be identifiable on the imaging studies.
