Earlier this year we released our own optimized and integrated BEAGLE implementation for SVS based on the BEAGLE 4.1 and optionally 4.0 algorithms. One of the commonly requested features since that released was to expand the algorithm implementation to be considerate of the parent-offspring relationship between samples to inform and improve the accuracy of the haplotype phasing.  With this information,… Read more »

Coming Soon! The genome Aggregation Database (gnomAD)

VarSeq Updated

Ever since the MacArther Lab announced the new gnomAD browser at last year’s ASHG conference, we have had many requests from our customers to make this new variant frequency source available within both VarSeq and SVS. This new dataset includes variants obtained from 123,136 exome sequences and 15,496 whole-genome sequences. In comparison to the original ExAC dataset which contained exomes… Read more »

Adding RSIDs to your SVS marker mapped spreadsheet

VarSeq Updated

In the new Genotype Imputation tool that is coming soon to SVS, allele encoding is an important part of matching data between the target and the reference panels. If the same platform provider is being used, then A/B encoding can be used. However, it’s better to use the Reference/Alternate allele encoding associated with AGCT format to ensure accuracy. If an… Read more »
