Variants pathogenicity categorization.
References | Categorization | Interpretation |
---|---|---|
Dorschner et al., 2013 | Pathogenic | Allele frequency of the identified variant is below cutoff AND segregation can be found in at least two unrelated families |
Likely pathogenic variant of uncertain significance (VUS) | Allele frequency of the identified variant is below cutoff AND identified in at least three unrelated individuals | |
VUS | Allele frequency of the discovered variant is below cutoff AND present in less than three unrelated affected individuals | |
Likely benign VUS | Allele frequency of the identified variant is below cutoff AND/OR seen in combination with a known pathogenic mutation | |
Richards et al., 2015 ACGM and AMP | Pathogenic very strong | Null variant (non-sense, frameshift, initiation codon, single or multiexon deletion) in a gene is a known mechanism of disease |
Pathogenic strong | Similar amino acid modification which was previously considered as pathogenic variant independent of nucleotide change | |
Pathogenic moderate | Localize in a mutational critical region and very important functional domain without benign variation | |
Pathogenic supporting | Cosegregation with disease located in many affected family members in a gene well known to be the cause the disease | |
Benign standalone | Allele frequency is greater than 5% in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium | |
Benign strong | Allele frequency is greater than expected for disorder | |
Benign supporting | Missense variant in a gene for which primarily truncating variants are known to cause disease | |
