Specifications for a DAF for gene-disease data

New AGR Disease Working Group specified DAF

• These specifications have been discussed and specified by the Disease Working Group of the AGR
• Annotations from the computational pipeline that WB currently has for assigning 'Potential models' will not be included in the MOD-specific DAFs. The plan is to have a separate AGR orthology pipeline to link human genes, orthologs from model organisms and disease.
• Note that all models are not in place yet in WB, though some of the data is already being curated in the Caltech Ontology Annotator curation tool for disease.

DAF columns and mapping of gene-disease data to columns

Column	Content	Required(R) Optional(O)	Cardinality	Example	Definition	Model tag	New/Exists	Comment
1	Taxon	R	1	taxon:6239	NCBI taxonomic identifier for the organism
2	DB Object Type	R	1	gene, allele, transgene, genotype, fish	The type of object being annotated
3	DB	R	1	WB	The database from which the identifiers in 'DB object ID' and 'DB Object Symbol' are drawn.
4	DB Object ID	R	1	WB:WBGene00004887	A unique identifier from the database in DB for the entity being annotated
5	DB Object Symbol	R	1	smn-1	A (unique and valid) symbol to which DB object ID is matched
6	Inferred Gene Association	O	0 or greater	WB:WBGene00004887	Database ID for inferred gene/marker association that can be made based on the DB object ID
7	Gene Product Form ID	O	0 or 1	UniProtKB id or PRO ID	this field allows the annotation of specific variants of that gene or gene product.
8	Experimental Conditions (to create the model)	O	0 or greater	standard conditions chemical/drug treatments (ChEBI ID, ZECO) dietary manipulations (specifiy entity) surgery/amputation bacterial/virus exposure (taxon ID)	Experimental/environmental (i.e. non-genetic) conditions required for the model, used particularly for induced models
9	Association Type	R	1	is_model_of causes_or_contributes_to_condition causes_condition contributes_to_condition is_marker_for||Relationship between the DB object and the disease
10	Qualifier	O	0 or 1	NOT	Used to indicate that the DB object is not associated with the DO term/association type
11	DO ID	R	1	DOID:12858	DO identifier for disease
12	With	O	0 or greater	DB:gene_symbol DB:gene_id DB:gene_symbol[allele_symbol] DB:allele_id||EITHER: - specifies additional genetic components of the model (where DB Object Type is not genotype/strain/fish) OR - specifies the orthologous (usually human) gene in annotations with ‘ISS/ISO’ evidence code
13	Modifier Association Type	O	0 or 1	condition_ameliorated_by condition_exacerbated_by	Relationship between the modifier and the disease model
14	Modifier - qualifier	O	0 or 1	NOT	Used to indicate DB object is not associated with the DO term/association type
15	Modifier (genetic)	O	0 or greater	DB:gene_symbol DB:gene_symbol(allele_symbol) DB:gene_id DB:allele_id||Specifies a genetic object (allele/gene) that modifies the disease model
16	Modifier - experimental conditions	O	0 or greater	standard conditions chemical/drug treatments (ChEBI ID, ZECO) dietary manipulations (specifiy entity) surgery/amputation bacterial/virus exposure (taxon ID)||Specifies a non-genetic object experimental condition that modifies the disease model
17	Evidence Code	R	1 or greater	EXP, IMP, IPM, IGI, IDA, IED, IEP, IAGP ISS, ISO, TAS, IC, IEA||From GO: Indicates the kind of evidence in the cited source that supports the disease annotation. If reference describes multiple methods that each provide evidence, then multiple annotations should be made with same DO term and different evidence codes.
18	Genetic sex	O	0 or 1	male/female/hermaphrodite	genetic sex of the model
19	DB:Reference	R	1	PMID:14978262	unique identifier(s) for a single source cited as an authority for the attribution of the DO ID to the DB object ID
20	Date	R	1	20090118	Date on which the annotation was made; format is YYYYMMDD
21	Assigned By	R	1	WB	The database which made the annotation - one of the values from the set of GO database cross-references

Current WormBase DAF (pre-AGR)

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

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