SLC2A10 and Andersen-Tawil syndrome: The incidence of ATS is not well known and, to date, only 106 patients have been described in literature, but its incidence is supposed to be even higher due to its very large and difficult-to-identify manifestation spectrum.2ATS is related to mutation of the gene SLC2A10 (chromosome 20q13.2), which encodes for the glucose transporter GLUT10.
