To annotate the full sepctrum of SNVs, please visit our new tool (

Welcome to the web portal of SNVrap ( The web portal provides comprehensive local database of human genome variants with a user-friendly web page that provides a one-stop annotating service which is both convenient and up-to-date. A query can be accepted as either a dbSNP Id or a chromosomal location and our system will instantly provide all the annotation information in an interactive LD panel. The system can also simultaneously prioritize this variant based on additive effect mode by corresponding annotation information and evaluate the variant effect that is then displayed in a prioritization tree. Furthermore, cohort sequencing continuously produces lots of un-annotated variants such as rare variants or de novo variants, and our system can even fit this data by accepting genomic coordinates (hg19) to offer maximal annotations.
