(A) An integrated model for collection, annotation, storage and visualization of candidate genes for ASD. (1) Candidate genes for ASD are compiled and maintained from an exhaustive search of scientific literature in the PubMed database maintained at NCBI (2) ASD candidates are classified into four categories. (3) Entries are organized in the database for search and retrieval. (4) User-friendly display of candidate genes at two levels for display and easy access with links to various external databases. (B) Search and display of candidate genes in AutDB. A search box is used to retrieve ASD candidate genes catalogued in AutDB using various gene attributes. The search results are displayed at two levels. At level 1, the gene entry is displayed in the summary row format showing: (A) gene symbol, (B) gene name, (C) chromosomal location, (D) Genetic category, (E) GAD and (F) OMIM links where available, (G) Number of autism-specific studies, (H) primary PubMed reference and (I) detail/edit button. A level 2, the entry is further displayed at a detail level in three-tier format showing: (1) gene summary with links to external databases such as Entrez Gene and UniProt, (2) relevance for autism displaying candidate gene report summary and (3) references arranged under three sub-headings: references for the candidate gene reports, highly referred and recent studies of the candidate genes.
