High- and Moderate-Risk Variants Among Breast Cancer Patients and Healthy Donors Enrolled in Multigene Panel Testing in a Population of Central Russia.

Assessments of breast cancer (BC) risk in carriers of pathogenic variants identified by gene panel testing in different populations are highly in demand worldwide. We performed target sequencing of 78 genes involved in DNA repair in 860 females with BC and 520 age- and family history-matched controls from Central Russia. Among BC patients, 562/860 (65.

Novel Pathogenic Variants in Hereditary Cancer Syndromes in a Highly Heterogeneous Cohort of Patients: Insights from Multigene Analysis.

Cancer is a major global public health challenge, affecting both quality of life and mortality. Recent advances in genetic research have uncovered hereditary cancer syndromes (HCS) that predispose individuals to malignant neoplasms. While traditional single-gene testing has focused on high-penetrance genes, the past decade has seen a shift toward multigene panels, which facilitate the analysis of multiple genes associated with specific HCS.

Gene Mutations: Implications for Hereditary Cancer Syndromes.

Malignant neoplasms, including pancreatic cancer and melanoma, are major global health challenges. This study investigates melanoma pancreatic syndrome, a rare hereditary tumor syndrome associated with gene mutations. mutations contribute to a lifetime risk of melanoma ranging from 28% to 67%.

[The structure of pathogenic germline variants in colorectal cancer in Moscow patients].

Objective: Describe the structure of pathogenic germline variants and clinical and anatomical features in colorectal cancer patients in Moscow.

Material And Methods: The whole genome sequencing results of patients with suspected hereditary cancer syndrome were evaluated. All identified genetic variants were validated using Sanger sequencing.
