Box 2: Some properties indexed by Gene

A current list can be displayed from Gene at any time by clicking on Preview/Index, selecting Properties from the pull-down menu, and clicking on Index. Definitions of all RefSeq types are maintained at the RefSeq homepage.

Property name Explanation
alive a current, primary record (i.e., not secondary or discontinued). The term secondary means a record that has been merged into another.
GeneRIF a record having one or more GeneRIF annotations attached
genetype miscrnagene encodes an RNA not in any of the specifics below
genetype otherof know type, but not any of the specific known categories
genetype protein codingencodes a protein
genetype pseudopseudogene
genetype rrnaencodes ribosomal RNA
genetype scrnaencodes small cytoplasmic RNA
genetype snornaencodes small nucleolar RNA
genetype snrnaencodes small nuclear RNA
genetype trnaencodes transfer RNA
genetype unknownthe type of gene is not known
has transcript variants a record having two or more associated RefSeq transcripts, i.e. splice variants. NOTE: this is limited to RefSeq annotation and should NOT be used to identify all genes exhibiting alternative splicing, promoter usage, and/or polyadenylation signals.
phenotypehas an associated phenotype
