A Multicenter Study of Genotype Variation/Demographic Patterns in 2475 Individuals Including 1444 Cases With Breast Cancer in Turkey.

Objective: Breast cancer (BC) is the most common cancer type in women and may be inherited, mostly in an autosomal dominant pattern. The clinical diagnosis of BC relies on the published diagnostic criteria, and analysis of two genes, and , which are strongly associated with BC, are included in these criteria. The aim of this study was to compare BC index cases with non-BC individuals in terms of genotype and diagnostic features to investigate the genotype/demographic information association.

Germline landscape of BRCAs by 7-site collaborations as a BRCA consortium in Turkey.

BRCA1/2 mutations play a significant role in cancer pathogenesis and predisposition particularly in breast, ovarian and prostate cancers. Thus, germline analysis of BRCA1 and BRCA2 is essential for clinical management strategies aiming at the identification of recurrent and novel mutations that could be used as a first screening approach. We analyzed germline variants of BRCA1/2 genes for 2168 individuals who had cancer diagnosis or high risk assessment due to BRCAs related cancers, referred to 10 health care centers distributed across 7 regions covering the Turkish landscape.

Nanobubble Ozone Stored in Hyaluronic Acid Decorated Liposomes: Antibacterial, Anti-SARS-CoV-2 Effect and Biocompatibility Tests.

Purpose: SARS-CoV-2-infected individuals may be asymptomatic, and therefore, the virus is highly contagious. We aimed to develop an agent to control viral replication in the upper respiratory tract and to prevent progression of the disease into the lower airways as well as inter-individual transmission. For this purpose, we investigated the antibacterial and antiviral activities of our novel nanobubble ozonated hyaluronic acid-decorated liposomal (NOHAL) solution, developed by using nanotechnology.

Clinical findings and mutational spectrum of neurofibromatosis type 1 patients in a single center of south part of Turkey.

Aim: The aim of this study is to determine the mutation spectrums and clinical characteristics of NF1 patients followed up in our center and to investigate whether there is a genotype-phenotype relationship.

Material And Methods: Sixty-three children and 34 relatives diagnosed with NF1 were included in the study. Age, gender, family history, clinical features, tumors detected in the patient at the time of diagnosis or during follow-up, orbital and cerebral magnetic resonance imaging (MRI) findings were recorded.

The emerging clinical relevance of genomic profiling in neuroendocrine tumours.

Background: Neuroendocrine tumours (NETs) arise from hormone-producing or nervous system cells and can develop from anywhere in the body. They have heterogeneous origins from skin to gastrointestinal track and a complicated histology. Thus, there is an inevitable need for genomic profiling to determine the exact genetics of each tumour for prognosis and treatment strategies to overcome the disease's complexity.

Current Status of Genetic Diagnosis Laboratories and Frequency of Genetic Variants Associated with Cystic Fibrosis through a Newborn-Screening Program in Turkey.

Background: Cystic fibrosis (CF) is the most common worldwide, life-shortening multisystem hereditary disease, with an autosomal recessive inheritance pattern caused by mutations in the cystic fibrosis transmembrane conductance regulator () gene. The national newborn screening (NBS) program for CF has been initiated in Turkey since 2015. If the immunoreactive trypsinogen (IRT) is elevated (higher than 70 μg/L in the second control) and confirmed by sweat test or clinical findings, genetic testing is performed.
