Methods

Publications were primarily identified using a Pubmed search. Additional searches were done using HuGE Net, Google Scholar and ISI Web of Science.

MeSH search terms used were:
("Epilepsy"[Mesh]) AND ("Gene Frequency"[Mesh] OR "Genetic Predisposition to Disease"[Mesh] OR "Genetic Variation"[Mesh] OR "Genotype"[Mesh] OR "Phenotype"[Mesh] OR "Polymorphism, genetic"[Mesh]) AND ("association" or “associated”).

Genetic association studies identified with the first-pass search terms were then used as the basis for the 'Related Articles' subsearch in Pubmed. Subsequent studies identified were then used for 'Related Articles' for 2 more iterations.

Data from the identified studies were extracted in a standardized manner and included in epiGAD.
