Background: The association between HER2 Ile655Val single nucleotide polymorphism and cancer is controversial.
Objectives: The aim of our study was to investigate this polymorphism in patients with ovarian cancer.
Patients And Methods: Genomic DNA was extracted from peripheral blood leukocytes of 107 patients and 130 healthy women. HER2 gene polymorphism was assessed by PCR-RFLP.
Results: No significant difference was observed in genotype and allele frequency between patient and control groups according to HER2 Ile655Val polymorphism. The disease stage, age, and histological type were also not associated with the polymorphism.
Conclusions: Our data showed that HER2 Ile655Val single nucleotide polymorphism was not significantly associated with onset, histological type, age, and stage of ovarian cancer in Iranian patients.

Background: The polymorphisms Arg72Pro in the TP53 gene (rs1042522) and Ile655Val in the HER2 gene (rs1136201) have been related to susceptibility to several types of cancer. Different studies show the association of these polymorphisms with breast cancer, so our aim in this study was to investigate whether the Arg72Pro and Ile655Val polymorphisms have any influence on the risk of developing breast cancer in women from the city of Macapá, Amapá, located in the brazilian amazon region.
Methods And Results: We then analyzed 80 DNA samples from women with breast cancer and 83 DNA samples from women without the disease, by the Restriction Fragment Length Polymorphism - Polymerase Chain Reaction (PCR-RFLP) technique.

Trastuzumab has improved the prognosis of HER2 positive breast cancer, but cardiotoxicity remains a concern. We aimed to identify risk factors for trastuzumab-induced cardiotoxicity, with an emphasis on the HER2 Ile655Val single nucleotide polymorphism. This single-center case-control study included 1056 patients with early-stage HER2 positive breast cancer that received adjuvant trastuzumab.

Chemotherapy is widely used in the treatment of cancer patients, but the cardiotoxicity induced by chemotherapy is still a major concern to most clinicians. Currently, genetic methods have been used to detect patients with high risk of chemotherapy-induced cardiotoxicity (CIC), and our study evaluated the correlation between genomic variants and CIC. The systematic literature search was performed in the PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), China Biology Medicine disc (CBMdisc), the Embase database, China National Knowledge Internet (CNKI) and Wanfang database from inception until June 2020.

Background: Breast cancer is a disease in which cell grows rapidly forming a mass in the breast. HER2 polymorphisms Ile655Val have been studied as biomarkers for breast cancer and may comprise a risk factor of cardiac toxicity for breast cancer-consuming trastuzumab.
Aim Of Work: In this study, we developed a simple, low cost, and rapid test to detect polymorphism at HER2 gene using SYBR Green I-based melting curve method.
