While more than 700 rare variants (allele frequency < 1%) in SLC2A10 gene are predicted to affect GLUT10 function (S2 Table and S3 Table), only a few have been demonstrated to cause ATS (S2 Table, labeled in red), and most variants are predicted to be benign or of uncertain significance. The gene discussed is SLC2A10; the disease is Andersen-Tawil syndrome.
