{Reference Type}: Case Reports {Title}: A case report of biallelic CHEK2 heterozygous variant presenting with breast cancer. {Author}: Soleimani T;Bourdon C;Davis J;Fortes T; {Journal}: Clin Case Rep {Volume}: 11 {Issue}: 1 {Year}: Jan 2023 暂无{DOI}: 10.1002/ccr3.6820 {Abstract}: Pathogenic germline variants in the CHEK2 gene have been shown to cause a moderate increased risk of breast cancer. Here, we present a striking CHEK2 family with a biallelic carrier of two frameshift pathogenic variants, to draw attention and to encourage a comprehensive genetic and cancer risk education for biallelic carriers of CHEK2 pathogenic variants.
