: Database ID of variant, grouping multiple observations of the same variant together, starting with the HGNC gene symbol, followed by an underscore (_) and a six digit number (e.g. DMD_012345). _000000 is used for variants where DNA was not analysed (change predicted from RNA analysis), variants seen in animal models or variants not seen in humans but functionally tested in vitro.
: MSCV|This MSCV ID is used to designate unique pathogenicity assessment even for the same variant but by different curators for different patients
: The dbSNP ID.
: Frequency in which the variant was found; e.g 5/760 chromosomes (in 5 of 760 chromosomes tested), 1/33 patients (in 1 of 33 patients analysed in study), 0.05 controls (in 5% of control cases tested).
: Variant Sources
: Reference to publication describing the variant, including links to OMIM (when available), PubMed or or other source, e.g. "den Dunnen ASHG2003 P2346".
