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.

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.

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.

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.

DNA change (genomic) (hg38): Description of variant at DNA level, based on the genomic DNA reference sequence (following HGVS recommendations).
