# Variant table columns The variant table displays all variants identified in your case, along with key annotations, quality metrics, pathogenicity data, and interpretation details. Each column provides specific information to help you review and prioritize variants effectively. This guide explains the meaning of each column for proband analysis and trio analysis, with sorting features and scoring details. ### 1. Core variant information


Variant details	Displays genomic coordinates and basic variant identifiers. SNV/Indel: Genomic position, nucleotide change, and dbSNP ID CNV/SV: Genomic coordinates and variant size Allows sorting by genomic start location.
Gene	Gene identifier. SNV/Indel/single-gene CNV: An HGNC-approved gene symbol Multi-gene CNVs: A list of HGNC-approved gene symbols and the number of genes included if only part of the list is shown. Tip: If only the beginning of the list is displayed in the table, you can see the full gene list in the pop-up tooltip.
Variant type	Specifies whether the variant is SNV, Indel, CNV, SV, STR, or other. Allows alphabetical sorting.
Main effect	Predicted effect(s) of the variant on protein structure and function (transcript-specific). By default the most severe effect is presented. Allows alphabetical sorting

### 2. Clinical and phenotypic data


Disease	Lists the count of disease associations, mode(s) of inheritance, and the name of one of the diseases. Tip: Hover over the line to see the full disease list in a pop-up window. Allows alphabetical sorting.
Tag	Variant tag assigned by Emedgene or by a user. Allows alphabetical sorting.
Known variants	Classification(s) of the variant in ClinVar and your curated variant database. Allows alphabetical sorting.
Variant notes	Indicates if Variant interpretation notes are available. Allows alphabetical sorting.

### 3. AI and Phenotype scoring


AI rank	Indicates potential causative variants: Most Likely Candidates and Candidates. Variants with identical scores share the same rank. Ranges from 1 to 220; lower numbers indicate higher rank. Case reanalysis causes Al ranks to be recalculated. Allows numerical sorting.
Phenomatch score	Proprietary phenotypic match score ranging from 0 to 1. Case reanalysis causes Phenomatch score to be recalculated. Allows numerical sorting.
PhenomeId score	Proprietary phenotypic match score outperforming previous Phenomatch models. Ranges from 0 to 2. A score of 0 means no match, a score above 0.15 suggests a moderate match, and scores above 0.7 indicate a high phenotypic match. Case reanalysis causes Phenomeld score to be recalculated. Allows numerical sorting.
