RCV000478991 | SCV000567894 | uncertain significance | not provided | 2015-09-12 | criteria provided, single submitter | clinical testing | This variant is denoted CHEK2 c.592+3_592+4delAA or IVS4+3_IVS4+4delAA and consists of a deletion of two nucleotides at the +3 to +4 position in intron 4 of the CHEK2 gene. The normal sequence with the bases that are deleted in braces is AGgt[aa]tatt, where the capital letters are exonic and lowercase are intronic. Multiple in silico models predict this variant to destroy the nearby natural donor site, and to possibly cause abnormal gene splicing. However, in the absence of RNA or functional studies, the actual effect of this variant is unknown. CHEK2 c.592+3_592+4delAA was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. Based on the currently available information, we consider CHEK2 c.592+3_592+4delAA to be a variant of uncertain significance. |
