Breast cancer is considered as the most common malignant disease, especially among Indian women that accounts for
the highest rate of morbidity and mortality. BRCA-1, ERBB-2 and TP-53 are amongst the high risk genes of breast cancer.
Mutations in these genes account for a considerably higher incidence of breast cancer initiation and development. In
breast cancer , BRCA-1 gene is considered as the most predisposing genetic factor. Similarly, ERBB-2 and TP-53 are also
observed as the main prognostic markers in the treatment of breast cancer. This study was designed to know the gene
expression profile of the molecular markers namely, breast cancer 1 (BRCA-1), human epidermal growth factor receptor
2 (ERBB-2) and tumor suppressor gene (TP-53) expression by the real time polymerase chain reaction (PCR). The
mutational analysis in particular exons of BRCA-1 (exon 11),ERBB-2 (exon 16) and TP-53 (exon 5) was further investigated
by Sanger-Sequencing in the above breast cancer patients of north Indian origin. The TP-53 mRNA levels have been
significantly expressed in cancer tissues as compared to the normal ones. Similar trends were observed with BRCA-1
and ERBB-2 mRNA expression as well. We conclude from this work that the differential gene expressions of BRCA-1,
ERBB-2 and TP-53 at the mRNA level may act as a diagnostic marker with a significant prognostic value in Breast cancer
patients.
