Evidence codes

From NMPDR Wiki

Evidence codes are used in the NMPDR to indicate why a particular functional role has been assigned to a gene. The evidence codes currently in use are shown below.

Code	Name	Explanation
IDA	Inferred from Direct Assay
IGI	Inferred from Genetic Interaction
TAS	Traceable Author Statement
ISU	In Subsystem Unique	The gene is the only one in the genome connected to the assigned functional role in the relevant subsystem.
IDU(n)	In Subsystem Duplicated	The gene is one of n genes from the genome connected to the assigned functional role in the relevant subsystem.
ICW(n)	In Cluster With	The gene is in a chromosomal cluster containing n other genes connected to the relevant subsystem.
FF	FIG Family	The gene is in a FIGfam with other genes having the functional role.
CWN	Clustered With Nonhypothetical
CWH	Clustered With Hypotheticals
DLIT	Direct Literature	The gene is assigned to this functional role in the literature.
ILIT	Indirect Literature	Similar genes are assigned to this functional role in the literature.
