| Gene Variant Descriptions | CHEK2 T410fs (corresponds to T367fs in the canonical isoform) results in a change in the amino acid sequence of the Chek2 protein beginning at aa 410 of 586, likely resulting in premature truncation of the functional protein (UniProt.org). T410fs results in decreased protein stability and reduced Chk2 phosphorylation in response to DNA damage (PMID: 16982735), and loss of Kap1 phosphorylation at serine (S)-473 in in vitro assays and in cell culture (PMID: 31050813, PMID: 34903604), and loss of kinase activity in an in vitro assay (PMID: 11053450). |
