We searched Gene Ontology (http://amigo.geneontology.org/cgi-bin/amigo/go.cgi) for the annotation of gene products for those genes in which confirmed SNPs of the follow up study are located. Gene Ontology provides a standardised vocabulary describing gene products in order to ensure uniformity across databases.49 Weinvestigated whether these genes share distribution patterns in Gene Ontology (GO) categories by mapping them to GO annotations.
