| Protein Effect | loss of function |
| Gene Variant Descriptions | CHEK2 C108R does not lie within any known functional domains of the Chek2 protein (UniProt.org). C108R confers a loss of function to Chek2 as demonstrated by decreased cell proliferation compared to wild-type Chek2 in a yeast assay (PMID: 30851065) and decreased Kap1 phosphorylation and Chek2 autophosphorylation in CHEK2-null cells in culture (PMID: 37449874). |
