Full data view for gene CHEK2

The variants shown are described using the transcript reference sequence.

Legend

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 effect on the function of the gene/protein, displayed in the format 'R/C'. R is the value reported by the source (publication, submitter) and this classification may vary between records. C is the value concluded by the curator. Note that in some database the curator uses Summary records to give details on the classification of the variant.Values used: '+' indicating the variant affects function, '+?' probably affects function, '-' does not affect function, '-?' probably does not affect function, '?' effect unknown, '.' effect was not classified.

Exon: Number of exon/intron containing variant; 2 = exon 2, 12i = intron 12, 2i_7i = exons 3 to 7, 8i_9 = border intron 8/exon 9.

DNA change (cDNA): Description of variant at DNA level, based on a coding DNA reference sequence (following HGVS recommendations); e.g. c.123C>T, c.123_145del, c.123_126dup.

Protein: Description of variant at protein level (following HGVS recommendations).

p.(Arg345Pro) = change predicted from DNA (RNA not analysed)

Review status: prueba

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.

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.

How to query this table

All list views have search fields which can be used to search data. You can search for a complete word or you can search for a part of a search term. If you enclose two or more words in double quotes, LOVD will search for the combination of those words only exactly in the order you specify. Note that search terms are case-insensitive and that wildcards such as * are treated as normal text! For all options, like "and", "or", and "not" searches, or searching for prefixes or suffixes, see the table below.

To sort on a certain column, click on the column header or on the arrows. If that column is already selected to sort on, the sort order will be swapped. The column currently sorted on has a darker blue background color than the other columns. The up and down arrows next to the column name indicate the current sorting direction. When sorting on any field other than the default, LOVD will sort secondarily on the default sort column.
