Thirty cases of pathogenic genes related to epilepsy were detected with mutations in the <i>SCN1A</i> gene (13 cases), <i>PCDH19</i> (4 cases), <i>ADGRV1</i> (3 cases), and <i>CACNB4</i> (2 cases) as well as one case each of mutations in <i>SCN2A</i>, <i>PRRT2</i>, <i>CACNA1A</i>, <i>CACNA1E</i>, <i>CACNA1H</i>, <i>KCNA2</i>, <i>CHD2</i>, and <i>KIAA2022</i>, which was identified as a novel gene mutation related to epilepsy. Here, CACNA1H is linked to epilepsy.
