VarSome & VarSome Clinical v.13.1.2

\n\n

Version 13.1.2 of VarSome and VarSome Clinical was released on 15 March 2025 to address minor performance issues:

\n\n

Users can now modify phenotypic data, including adding phenotypic data to finished analyses
Fix of potential failures of multi-sample analyses using existing analyses
\"Sample metrics\" column display has been updated
\"CNV Gene Lists\" can now be launched from the \"Action Menu\"
Refinements were also made to the\u00a0somatic classifier\u00a0to address an issue with how Jax CKB determines variant effect that was leading to some variants being incorrectly reported as relevant. We have implemented an overrule to the \"Protein Effect\" information coming from Jax CKB, whereby if the germline classifier indicates that a variant is Benign or Likely Benign \"Protein Effect\" data from Jax CKB will not be considered. We have also upgraded Levels Dx2, Dx3, Px2, and Px3 coming from OncoKB to be accounted for as Tier I evidence.

\n", "Gene statistics": "

This table summarises the variants reported in\u00a0UniProt, ClinVar, LOVD, MitoMap, VarSome & PubMed 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\u00a0UniProt, ClinVar, LOVD, MitoMap, VarSome & PubMed 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.

Examples:

\n\n

\"exon 230 of 313, pos 277-286 of 309\": this variant (most likely a deletion of 10bp)\u00a0affects bases 277 to 286 of the reference exon, whose length is 309

\n\n

\"intron 2\u00a0of 16, pos 1\u00a0of 8925\": this variant affects the first base\u00a0of the second intron (between second and third exon), whose length is 8925. This transcript has 16 introns and 17 exons.

\n", "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.
