Release notes

\n", "VEST3": "The Variant Effect Scoring Tool (VEST3) predicts missense variants and is based on a supervised machine learning algorithm (random forest) that utilizes 86 quantitative sequence features. The training set of this tool includes known deleterious missense variants from the Human Gene Mutation Database and common (>1% allele frequency) variants from the Exome Sequencing Project (ESP) population.", "Orphanet": "A reference portal of rare diseases and orphan drugs providing a wide range of services, from inventory and classification of diseases to assistance-to-diagnosis tools.", "Ensembl": "A database of genomic information for human and model organisms, created as a joint project between the EBI and the Welcome Trust Sanger Institute.", "RefSeq transcripts": "A collection of the most comprehensive and well-annotated non-redundant set of transcripts, which are provided by RefSeq, a database built by the NCBI.", "Equivalent indels": "

Insertions and deletions often have multiple equivalent representations.

\n\n

For example, for the\u00a0simple sequence AAAAAAAAA, a deletion of the first base is equivalent to a\u00a0deletion of the second or\u00a0the last base. This is because the resulting\u00a0sequence\u00a0is the same.

\n\n

We have taken\u00a0care to correctly match equivalent indels.\u00a0We match every\u00a0variant you query to its equivalents in all of the databases featured. If the variant you enter does not appear exactly the same in the results, it's because we have replaced it by its equivalent that matches our databases. For example, deletion \u00a013:38320600:AA:\u00a0will appear in position\u00a038320595 rather than the position entered.

This table summarises the variants reported in UniProt, ClinVar & VarSome user entries for a given gene. This is useful in order to obtain some high-level insights into the modes of pathogenicity for that gene, for example whether synonymous variants mostly benign, or whether the majority of frame-shift variants are pathogenic.

\n\n

Methodology

\n\n

The aggregate counts are obtained by scanning all the variant classifications in the the UniProt, ClinVar and VarSome databases. For each variant we identify which gene(s) it\u00a0is on. We then iterate through all known transcripts for that gene, and identify the coding impacts (frame-shift, non-sense etc.). Finally we aggregate the counts by gene, coding impact and pathogenicity.

\n\n

In order to avoid double-counting, each variant is only recorded once:

\n\n

in the event that the variant is classified differently by several sources, the \u201cmost definitive\u201d classification is picked. If there is still a conflict the most pathogenic classification will supercede the others.
if different transcripts result in multiple coding impacts, we pick the first found in the following order: exon-deletion, non-sense, frame-shift, stop loss, mis-sense, inframe-indel, synonymous, and finally non-coding. This allows regulatory or non-coding sections of genes to still be reported correctly.

\n", "Rsid": "

A unique identifier\u00a0prefixed by\u00a0'rs' assigned by the dbSNP database to each variant. An rsid may correspond to several alleles;\u00a0an insertion or deletion (\"indel\") may have multiple rsids.

\n", "SNOMED_CT": "Systematized NOMenclature of MEDicine Clinical Terms (SNOMED_CT) is a database that provides the most comprehensive, multilingual clinical healthcare terminology in the world including clinical findings, symptoms, diagnoses, procedures and body structures.", "Germline variant": "A genomic variation that is inherited from the parents. It is present in all cells of the organism, including the germ cells, and can be transmitted to the offspring.", "pNull": "

\n", "Number of queries in this region": "

Number of queries on VarSome for the region displayed. This number is updated\u00a0regularly but not instantly.

\n", "Transcript": "

A segment\u00a0of DNA that is\u00a0transcribed to RNA. Gene usually have\u00a0many alternative transcripts derived through different processes, including alternative splicing, exon skipping, and intron retention. Alternative transcripts are effectively different combinations of exons of the same gene.

MKL, in addition to the original FATHMM, also predicts noncoding effects by integrating functional annotation information from the ENCODE. Range 0 to 1.
