The server accepts list of variants, one variant per line, plus optional text describing your variants,

in genomic coordinates, "+" strand assumed :

  <genome build>,<chromosome>,<position>,<reference allele>,<substituted allele>

Genome build is optional (build 19 assumed), accepted values: 'hg19' and 'hg38'

Examples:

  hg38,13,32338418,G,T   BRCA2

  hg19,7,55211080,G,A   EGFR

  7,55211080,G,A   EGFR

 

or in protein space:

  <protein ID> <variant> <text>,

where <protein ID> can be :

- Uniprot protein accession (e.g. EGFR_HUMAN)

- NCBI Refseq protein ID (e.g. NP_005219)

Examples:

  EGFR_HUMAN R521K

  EGFR_HUMAN R98Q Polymorphism

  EGFR_HUMAN G719D disease

  NP_000537 G356A

  NP_000537 G360A dbSNP:rs35993958

  NP_000537 S46A Abolishes phosphorylation

 

ID types can be mixed in one list in any way.

 

The server maps each variant to both Uniprot and Refseq protein sequences (if possible).

If the reference residue in the Uniprot protein sequence is

different from the one indicated in your variant the analysis will not be performed.

For non-human variants please use Uniprot IDs as mapping to Refseq is not supported.

 

Uniprot IDs are used to extract information about domain boundaries (Pfam, Uniprot), annotated functional regions (Uniprot),

protein-protein interactions (Piana). Refseq protein IDs are used to extract known alterations in cancer (COSMIC),

SNPs (dbSNP) and known role in cancer (CancerGenes).

 

The server determines domain boundaries (using Pfam or Uniprot) for the region with the variant and builds multiple

sequence alignment using all Uniprot protein sequences or uses existing one from the repository. To obtain the list

of existing alignments in the repository for a giver protein please see WEBAPI section below.

For each variant the server provides the following annotations (this description also available as a tooltip in the main table) :
