Please note that a short description of a certain column can be displayed when you move your mouse cursor over the column's header and hold it still. Below, a more detailed description is shown per column.

Effect: The variant's affect on a protein's function, in the format Reported/Curator concluded; '+' indicating the variant affects function, '+?' probably affects function, '-' does not affect function, '-?' probably does not affect function, '?' effect unknown, '.' effect not classified.

Allele: On which allele is the variant located? Does not necessarily imply inheritance! 'Paternal' (confirmed or inferred), 'Maternal' (confirmed or inferred), 'Parent #1' or #2 for compound heterozygosity without having screened the parents, 'Unknown' for heterozygosity without having screened the parents, 'Both' for homozygozity.

DNA change (genomic) (hg19): Description of variant at DNA level, based on the genomic DNA reference sequence (following HGVS recommendations).

• g.12345678C>T
• g.12345678_12345890del
• g.12345678_12345890dup

Reference: Reference to publication describing the variant, including links to OMIM (when available), PubMed or or other source, e.g. "den Dunnen ASHG2003 P2346".

DB-ID: 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.

Frequency: 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).
