Název v původním jazyce

Two new CHEK2 germ-line variants detected in breast cancer/sarcoma families negative for BRCA1, BRCA2, and TP53 gene mutations

Popis výsledku v původním jazyce

CHEK2 gene mutations occur in a subset of patients with familial breast cancer, acting as moderate/low penetrance cancer susceptibility alleles. Although CHEK2 is no longer recognized as a major determinant of the Li-Fraumeni syndrome, a hereditary condition predisposing to cancer at multiple sites, it cannot be ruled out that mutations of this gene play a role in malignancies arising in peculiar multi-cancer families. To assess the contribution of CHEK2 to the breast cancer/sarcoma phenotype, we screened for germ-line sequence variations of the gene among 12 probands from hereditary breast/ovarian cancer families with one case of sarcoma that tested wild-type for mutations in the BRCA1, BRCA2, and TP53 genes. Two cases harbored previously unreported mutations in CHEK2, the c.507delT and c.38A } G, leading to protein truncation (p.Phe169LeufsX2) and amino acid substitution (p.His13Arg), respectively.
