ATM and PALB2 variant curation guidelines progress update: ClinGen Hereditary Breast, Ovarian, and Pancreatic Cancer Variant Curation Expert Panel

This poster has been honored with the "Poster of Distinction" at CGA-ICG

Take home points: 

1. Here present customization of the original ACMG/AMP rules for ATM and PALB2.  

2. Recommendations include exclusion of >40% of codes for variant interpretation and a further gene- and disease-specific modification for most of the others. 

3. In a pilot study of >30 variants for each gene resulted in a majority agreement with consensus ClinVar interpretations reduced conflicting/VUS interpretations from 11 to 5 for ATM and from 13 to 7 for PALB2.  

4. Gene specific variant interpretation guidelines can help resolve uncertain and discrepant variant classifications.
