The OMIM epileptic encephalopathy genes plotted by year of data entry into OMIM (year of establishing the OMIM entry) versus the fraction of PubMed publications related to epilepsy compared to all publications for a given gene. The diameter of the bubble refers to the number of epilepsy-related publications for a given gene. It is obvious that this chart is strongly dominated by SCN1A, highlighting the role of this gene for human epilepsies. The original table from which this chart was derived can be found here.
