GeT-RM partnered with ClinGen to develop a publicly available list of expert curated, clinically important variants. This list serves as a resource for designing comprehensive validation studies. It is also used for creating in silico reference materials for clinical genomic test development and validation.10 ClinGen Variant Curation Expert Panels nominated 546 pathogenic and difficult to detect variants in 84 disease-associated genes.
