The Cancer Predisposition Sequencing Reporter (CPSR) is a computational workflow that interprets and classifies the clinical significance of germline DNA variants identified from next-generation sequencing in the context of cancer predisposition and inherited cancer syndromes. The workflow can also report incidental findings (ACMG v3.2).

The CPSR workflow is integrated with the framework that underlies the Personal Cancer Genome Reporter - PCGR. While PCGR is intended for reporting and analysis of somatic variants detected in a tumor, CPSR is intended for reporting and ranking of germline variants in protein-coding genes that are implicated in cancer predisposition and inherited cancer syndromes.

CPSR accepts a query file from a single case/patient, containing raw germline variant calls encoded in the VCF format (i.e. SNVs/InDels). A comprehensive set of virtual cancer predisposition gene panels harvested from the Genomics England PanelApp allows the user to flexibly put a restriction on which genes and findings are displayed in the cancer predisposition report.

Snapshots of sections in the quarto-based cancer predisposition genome report (artificial sample, with more findings than usual) are shown below:
