SCN1A and epilepsy: In this study, whole-exome sequencing (WES) for one family and targeted sequencing was done for 25 samples having epilepsy and our results showed that the family had novel missense variant c.1603C>T, p. Arg535Cys in exon 10 of SCN1A gene and c.1212A>G p.Val404Ile in 10 unrelated patients along with a mutation in CACNB4 gene in exon 3 c.78_79insG, p.Asp27Glyfs*26 in three different patients from the cohort.
