BRCA-Q Real-Time PCR Kit

Product Overview


Mutations in the BRCA1 and BRCA2 genes are the two most common genetic alterations in the high-penetrance form of hereditary breast and ovarian cancer. BRCA1 and BRCA2 genes produce tumour suppressor proteins, and any changes or mutations in these genes can lead to significantly increased risk of developing breast, ovarian, and prostate cancer. Approximately 55 to 72% of women who inherit a harmful BRCA1 variant and 45 to 69% of women who inherit a harmful BRCA2 variant will develop breast cancer by 70 to 80 years of age. Early and precise detection of these mutations is essential not only for confirming diagnosis but also for identifying at-risk individuals, guiding preventive strategies, facilitating family counselling, and enabling targeted therapy selection.

To meet this critical need, Genes2Me introduces the BRCA-Q Real-Time PCR Kit — an advanced in vitro diagnostic solution designed for the qualitative detection of BRCA1 and BRCA2 mutations in genomic DNA extracted from blood (EDTA) and formalin-fixed paraffin-embedded (FFPE) tissue. The kit detects and differentiates eight genetic polymorphisms associated with breast and ovarian cancer across seven BRCA1 variants and one BRCA2 variant, empowering laboratories with accurate, fast, and reproducible results for cancer risk assessment, diagnosis, and treatment planning.

How the Assay Works


The BRCA-Q Kit uses a real-time PCR protocol based on amplification of specific target DNA sequences, followed by detection using melting curve analysis. The assay employs fluorescent, allele-specific probes — each designed to selectively bind one of the two alleles of the target gene. Three distinguishably labelled probes carry different reporter dyes: FAM for the wild-type (WT) allele, HEX for the mutant (MT) allele, and Cy5 for the internal control (IC).

Following amplification, melting curve analysis of the amplicon-probe complexes is performed. During melting, changes in fluorescence are continuously monitored by the real-time thermal cycler. When a probe is perfectly complementary to the target DNA, it exhibits a higher melting temperature (Tm), whereas partial complementarity results in a lower Tm. Result interpretation is based on observed melting temperatures, allowing accurate discrimination between wild-type and mutant allelic variants. The Cy5-labelled internal control validates DNA input, reagent integrity, and PCR performance in every run, with a Ct value cut-off of 32 for differentiating valid from invalid results.

Clinical Relevance


BRCA1 and BRCA2 mutation testing is central to hereditary cancer risk assessment and the clinical management of breast, ovarian, and prostate cancers. Comprehensive detection and allelic differentiation of seven BRCA1 mutations and one BRCA2 mutation provides oncologists and genetic counsellors with actionable insights to stratify patient risk, guide preventive care, and tailor targeted therapies. With 99% clinical sensitivity and 99% clinical specificity, and a limit of detection of 1 genome equivalent per 1.0 ng of human DNA per reaction, the BRCA-Q Real-Time PCR Kit enables early identification of mutation carriers and plays a crucial role in reducing cancer mortality and improving patient outcomes.

Key Features & Benefits


Comprehensive Mutation Coverage

Detects and discriminates eight clinically significant genetic polymorphisms — seven BRCA1 mutations (185delAG, 4153delA, 5382insC, 3819delGTAAA, 3875delGTCT, 300T>G [Cys61Gly], 2080delA) and one BRCA2 mutation (6174delT) — providing a complete mutation profile for cancer risk assessment and therapy guidance.

Three-Channel Multiplex Design

Allele-specific probes with three reporter dyes — FAM for wild-type alleles, HEX for mutant alleles, and Cy5 for the internal control — enable simultaneous detection and accurate discrimination of normal and mutant allelic variants in a single reaction.

Melting Curve Analysis

Post-amplification melting curve analysis enables precise differentiation of wild-type and mutant alleles based on distinct melting temperatures, allowing confident allelic discrimination even in heterozygous samples.

Internal Control Assurance

Built-in Cy5-labelled internal control validates DNA input, reagent integrity, and PCR performance in every run; a Ct value cut-off of 32 differentiates valid from invalid results.

Data Analysis and Report


BRCA1 BRCA2

When the Ct value of the sample to be tested is outside the reference range and there is a typical S-shaped amplification curve, the test result is positive; When the Ct value of the sample to be tested is within the reference range, or the Ct value is outside the reference range but there is no typical S-shaped amplification curve, the test result is negative.
