| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | CHEK2 G229S lies within the protein kinase domain of the Chek2 protein (UniProt.org). G229S results in reduced phosphorylation of Chek2 and Kap1 upon ionizing radiation in culture (PMID: 34903604), and therefore, is predicted to lead to a loss of Chek2 protein function. |
