Variant Interpretation:
What is the protocol for interpreting a variation as a VUS?
Help
Variations are first classified based on frequency (according to databases such as 1000 Genomes and GnomAD). Rare variations are classified as VUS if: 1) the variation has not been reported previously and available information (effect prediction models, conservation scores and patient data) does not allow other classification; 2) there are … View more

Alamut® Visual (includes splice site prediction tools, SIFT, PolyPhen2, MutationTaster, frequency data).
Laboratory's policy on reporting novel variations Help
Novel variations are interpreted in the context of the patient’s data as well as information known about the gene that it was found in. If possible association with patient’s phenotype is suspected, novel variations are reported with a short description of the possible effect and population frequencies.
