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.

Affects function: 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 = from intron 2 to intron 7, 8i_9 = intron 8/exon 9 boundary, _1 = 5' to exon 1, 18_ = 3' of exon 18, _1_18_ = encompassing the entire 18-exon gene

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. For deletions/duplications extending beyond the reference transcript resp. {0}/{2} is used to replace del/dup. Extent of the deletion/duplication should be specified using the genomic description (g.). "-" indicates the variant described on genomic level does not affect the coding DNA reference sequence.

Haplotype: haplotype on which variant was found

RNA change: description of variant at RNA level (following HGVS recommendations).

• r.123c>u
• r.? = unknown
• r.(?) = RNA not analysed but probably transcribed copy of DNA variant
• r.spl? = RNA not analysed but variant probably affects splicing
• r.(spl?) = RNA not analysed but variant may affect splicing
• r.0? = change expected to abolish transcription

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

• p.(Arg345Pro) = change predicted from DNA (RNA not analysed)
• p.Arg345Pro = change derived from RNA analysis
• p.? = unknown effect
• p.0? = probably no protein produced

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.
