The VAAST Variant Prioritizer (VVP): ultrafast, easy to use whole genome variant prioritization tool

Abstract: BackgroundPrioritization of sequence variants for diagnosis and discovery of Mendelian diseases is challenging, especially in large collections of whole genome sequences (WGS). Fast, scalable solutions are needed for discovery research, for clinical applications, and for curation of massive public variant repositories such as dbSNP and gnomAD. In response, we have developed VVP, the VAAST Variant Prioritizer. VVP is ultrafast, scales to even the largest variant repositories and genome collections, and its outp… Show more

“…The 2391 trios were analyzed as trios using the VAAST Variant Prioritizer (VVP) 35 and VAAST burden tests. A typical VVP command was: VVP -d vvp_v2_background/1KG.050417.vvp.db -i 1-00004.vcf.gz -v CSQ,3,6,0,15 -c -n 1 -o 1-00004.scored_variants.out>1-00004_VVP.out.…”

“…In contrast, we identified many more candidate recessive genotypes on average, 1.3 proband −1 , compared to 0.2 proband −1 reported previously 3 . The increased numbers result from VAAST’s ability to identity compound heterozygous genotypes for which the combined burden of two moderately damaging variants is equal to that of a single, severely damaging de novo variant 19,20,35,36 . By contrast, the PCGC’s previously reported recessive genotypes 3 were restricted solely to cases for which both variants were loss-of-function alleles or missense variants predicted to be maximally damaging by MetaSVM.…”

“…As a background population, a VCF file with variants from 1000 Genomes phase 3 [74] were run through the same workflow. A VVP background database was made from the 1000 Genome filtered variants using the build_background function of VVP [121]. This background database and the filtered VCF file of variants discovered in this cohort were used as inputs to VVP to prioritize cohortdiscovered variants, which were then passed to VAAST3 to be scored and ranked.…”

“…Furthermore, the overwhelming majority of VOUS alleles are believed to be benign (Pelak et al, 2010). Thus, the ability to efficiently identify benign variants among a set of VOUS alleles, without requiring the resource‐intensive process of manual downstream review, has been a recent focus of several genetic test providers and genetic studies (Bosio et al, 2019; Chen, 2019; Du et al, 2019; Flygare et al, 2018; Padilla et al, 2019; Ravichandran et al, 2019; Roca et al, 2018; Zhou & Zhao, 2018). Of the existing methods that are commonly used to identify benign variants, exclusion by allele frequency is among the most powerful and amenable to automation.…”
