Candidate genes reported in association with Jeavons syndrome include SYNGAP1, KIA02022/NEXMIF, RORB, CHD2, GABRA1, SLC2A1, KCNB1, and NAA10, which are involved in neuronal development, migration, function, and genetic regulation (25). This evidence concerns the gene KCNB1 and epilepsy with eyelid myoclonia.
