Help Variant Prediction


Variant Prediction

We use SnpEff to perform variant prediction. Variants are labeled as having a LOW, MODERATE, or HIGH impact based on the location and nature of the variant. We do not include MODIFIER annotations provided by SnpEff. Variant impacts are detailed within The Sequence Ontology Project.
