Dr Laveniya Satgunaseelan is a pathologist in the Department of Neuropathology at Royal Prince Alfred Hospital, Sydney. Her main role is in the provision of molecular neuropathology services. Laveniya is an active member of the NIH ClinGen Somatic Cancer Working Group, where she is the co-chair of the Solid Tumor Taskforce and Histone H3 Somatic Cancer Variant Curation Expert Panel. She also serves as editor of the CNS chapter of the Compendium of Cancer Genomic Aberrations (CCGA). Locally, Laveniya is the current secretary/treasurer of the Australia and New Zealand Society of Neuropathology.

The Clinical Genome Resource (ClinGen) Somatic Clinical Domain Working Group (CDWG) (https://www.clinicalgenome.org/working-groups/clinical-domain/somatic-cancer-cdwg/) is an international multi-institutional effort to develop and standardize data curation guidelines for somatic genomic alterations in cancer. The recognition of a demanded but missing focus specific for solid tumors, in light of expanded testing options and the increased complexity of tumor classification systems that incorporate molecular information, led to the formation of the Somatic Cancer Solid Tumor Taskforce (STT) under the CDWG. The newly formed STT comprises 55 members from academia and industry, combining their expertise in variant curation in solid tumors. Our primary aim is the curation of somatic genetic alterations in solid tumors into the Clinical Interpretation of Variants in Cancer database (CIViC; civicdb.org), with the objective of supporting the clinical interpretation of difficult to curate alterations. A curation focus (e.g., EGFR fusions) is chosen at each quarter with monthly reviews of CIViC evidence items contributed by STT members. Half yearly, assertions of clinical significance regarding the alterations are formulated in CIViC. Where curation challenges persist, formation of a Somatic Cancer Variant Curation Expert Panel (SC-VCEP) will be recommended. For example, an SC-VCEP focusing on curation of single nucleotide variants in the FGFR3 gene in urothelial cancer is currently active in Step 2 of the ClinGen SC-VCEP approval process, developing classification rules specific to somatic variants in FGFR3. The STT is seeking invaluable input from the CGC community on solid tumor areas presenting clinical interpretation challenges.
