Based on the analysis of patients with Peutz-Jeghers syndrome (PJS), Serine threonine kinase11 (STK11) is known as a tumor suppressor gene, which involved in cell polarization, regulation apoptosis, and DNA damage response. In this case report study, we examined STK11 gene sequencing 42-year-old woman mucocuta neous pigmentation positive family history. Endoscopy colonoscopy showed >1000 polyps throughout stomach/colon (PJ-type hamartomas). The larger polyp stomach was resected small bowel...

Abstract Background Approximately 5% of colorectal cancers (CRCs) are hereditary. Lynch syndrome (LS), also known as hereditary nonpolyposis cancer (HNPCC), is the most common form recognized CRC. Although Iran, a developing country, has high incidence CRC, spectrum variants yet to be thoroughly investigated. Aims This study aimed investigate pathogenic and non‐pathogenic in MLH1 MSH2 genes Iranian patients with suspected (sLS). Methods results In present study, 25 peripheral blood samples...

Aim: To investigate the correlation between Epstein–Barr virus (EBV) variants and EBV-associated gastric cancer (EBVaGC) in Iran. Materials & methods: Biopsies from 21 (4 positive EBER-ISH 17 negative EBER-ISH) 11 gastritis patients were analyzed using nested PCR sequencing. Results: Genotype 1 (75%) was predominant EBV genotype. The P-thr variant most common all groups (positive 75%, 76.4%, 81.8%), followed by P-ala. Additionally, LMP1 strain Med. Sequencing analysis revealed a strong type...
