| Research Abstract |
More than 650 mutations in the voltage-gated sodium channel subunit gene SCN1A have been identified in epileptic patients with benign and severe phenotype. However, the reason why similar missense mutations in SCN1A resulting in different phenotypes has not been fully clarified yet. We analyzed genotype-phenotype correlation and constructed SCN1A-related epilepsy phenotypes prediction model based on the effects of physicochemical property changes by amino acid substitution. In the results, we suggested that several physicochemical property related to the differentiation of epilepsy phenotypes, and the prediction model based on these physicochemical property can classify severe and benign epilepsy phenotypes with high accuracy.
