| Gene Variant Descriptions | CHEK2 N290Ifs*15 indicates a shift in the reading frame starting at amino acid 290 and terminating 15 residues downstream causing a premature truncation of the 543 amino acid Chek2 protein (UniProt.org). N290Ifs*15 has not been characterized, however, due to the effects of other truncation mutations downstream of N290 resulting in disruption of the protein kinase domain (PMID: 11053450, PMID: 16982735, PMID: 31050813), is predicted to lead to a loss of Chek2 protein function. |
