SIFTDbColumns: SIFTDb Columns
Description
Description of the SIFT Sqlite Database ColumnsColumn descriptions
These column names are displayed when columns
is called on a
SIFTDb
object.
- RSID : rsid
- PROTEINID : NCBI RefSeq protein ID
- AACHANGE : amino acid substitution; reference aa is preceeding,
followed by the position and finally the snp aa
- METHOD : method of obtaining related sequences using PSI-BLAST
- AA : either the reference or snp residue amino acid
- PREDICTION : SIFT prediction
- SCORE : SIFT score (range 0 to 1)
- TOLERATED : score is greater than 0.05
- DAMAGING : score is less than or equal to 0.05
- NOT SCORED : no prediction is made if there are less than
2 homologous sequences that have an amino acid
at the position of the given SNP or if the SIFT
prediction is not available
- MEDIAN : diversity measurement of the sequences used for
prediction (range 0 to 4.32)
- POSITIONSEQS : number of sequences with an amino acide at the
position of prediction
- TOTALSEQS : total number of sequences in alignment
