Out of these overlapping genes, FOXO4, GRM5, RIMS1 and NELL2, were found to be associated with neurological diseases in recent publications [GRM5 (24–26), RIMS1 (27), FOXO4 (28), NELL2 (29)] though they were not yet annotated with any neurological disease terms in the database (RGD, rgd.mcw.edu, last accessed October 2012). This evidence concerns the gene RIMS1 and nervous system disorder.
