| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | CHEK2 K135Nfs*26 indicates a shift in the reading frame starting at amino acid 135 and terminating 26 residues downstream causing a premature truncation of the 543 amino acid Chek2 protein (UniProt.org). K135Nfs*26 results in reduced Kap1 phosphorylation upon ionizing radiation in cell culture (PMID: 34903604), and therefore, is predicted to lead to a loss of Chek2 protein function. |
