Interactive Variant Analysis (IVA) tool allows for whole genome variant browsing and analysis. This interactive tool allows finding genes affected by deleterious variants that segregate along family pedigrees, case-controls control or sporadic samples.

IVA is developed and maintained at University of Cambridge and CIPF, it is freely available at

Main Features

  • Allow to load VCF files and samples together with clinical data
  • High-performance and scalable VCF and gVCF indexing
  • VCF normalization and variant annotation
  • Clinical interpretation analysis of samples and families
