GAF 2.0 for gene-disease data includes all genes with the Experimental_model and/or Potential_model tags.

Format: The gene association file is a 17 column tab-delimited file, where 11 columns have to have data and 6 are optional.


Mapping of GAF column to gene-disease data
Column Content Required? Cardinality Example
1 DB required 1 WB
2 DB Object ID required 1 WBGene00007799
3 DB Object Symbol required 1 nrx-1
4 Qualifier optional 0 or greater (no value, leave empty)
5 GO ID required 1 DOID:0060041
6 DB:Reference (|DB:Reference) required 1 or greater
(separate values with pipes)
WBPaper00041363|WBPaperXXXXXXXX
7 Evidence code required 1 IMP or ISS (use 'IMP' for Experimental_model
genes and ISS for Potential_model genes)
8 With (or) From optional 0 or greater
(separate values with pipes)
OMIM:600565|OMIM:600566
9 Aspect required 1 D (D for disease ontology, all annotations
have this value)
10 DB Object Name optional 0 or 1 (no value, leave empty)
11 DB Object Synonym (|Synonym) optional 0 or greater (no value, leave empty)
12 DB Object Type required 1 gene (all annotations have this value)
13 Taxon required 1 or 2 taxon:6239
14 Date required 1 20130422 (this is the date of annotation dumped under Date_last_updated;
for potential_model genes, use the date on which the OMIM homology script is run)
15 Assigned By required 1 WB
16 Annotation Extension optional 0 or greater (no value, leave empty)
17 Gene Product Form ID optional 0 or greater (no value, leave empty)
