METHOD FOR MOLECULAR-GENETIC DIAGNOSIS OF HEREDITARY BREAST CANCER Russian patent published in 2019 - IPC G01N33/574 C12Q1/6827 C12Q1/6886 

Abstract RU 2702755 C1

FIELD: medicine.

SUBSTANCE: invention relates to medicine. What is presented is a method for molecular genetic diagnosis of hereditary breast cancer. Isolated DNA is tested for 5382insC mutation in the BRCA1 gene by real-time allele-specific PCR. In case of positive result, this mutation is searched for among blood relatives of the patient. If 5382insC mutation is absent, the patient's whole coding part of BRCA1/2 genes with adjoining sections of introns and regulatory regions is analyzed by a new generation sequencing method. If pathogenic mutations are absent, no mutations in BRCA1/2 genes are observed in the patient. If a pathogenic mutation is found, the patient is diagnosed with a genetic predisposition to breast cancer and similar mutations are sought for in blood relatives. If pathogen mutation is absent, blood relatives conclude that they do not have mutations in BRCA1/2 genes.

EFFECT: invention provides higher diagnostic efficiency.
