Background: Nephropathy is the most important leading cause of end stage renal failure in type 2 diabetic patients, so numerous studies were done to diagnose and evaluate risk factors of diabetic nephropathy (DN). Some gene polymorphisms may be associated with progression or regression of DN, so the aim of this study was to compare prevalence of eNOS gene polymorphism in diabetic patients with controls and its association with diabetic nephropathy.
Materials And Methods: In a cross-sectional study, 94 type 2 diabetic patients and 94 normal participants were enrolled. Patients without retinopathy were excluded from this study. For all of the patients, fasting blood sugar (FBS), 2 hours post-prandial (BS), Blood Urea Nitrogen (BUN), Creatinine (Cr), 24 hours urine protein were measured in the case group. Endothelial nitric oxide synthetase gene polymorphism was evaluated in the case and control groups.
Results: There was no significant difference based on age and sex between patients in case and control groups. GG genotype of eNOS was less common in the patient group compared to control group. There was no difference between prevalence of TT, GT or GG genotype based on age and sex. There was no correlation between diabetic retinopathy or proteinuria and genotypes of eNOs.
Conclusion: The study showed that in type 2 diabetic patients, NOS gene polymorphism was more common compared to normal population; however, there is no correlation between this gene polymorphism and proteinuria or retinopathy in these patients.

Genomic selection is a widely used quantitative method of determining the genetic value of an individual from genomic information and phenotypic data. In this study, we used a large, multi-year training population of 3248 individuals from the University of Florida strawberry (Fragaria × ananassa Duchesne) breeding program. We coupled this training population with a test population of 1460 individuals derived from 20 biparental families.

Red deer is a species of family Cervidae that is widely distributed in the world and is often raised to provide antlers, as a trophy or traditional medicine materials, and meat. Currently, the whole genomic data for red deer are very limited. Qingyuan Wapiti (QYW), China's first breed of red deer by artificial breeding, is well known for its high yield of antlers and large body size.

Background: A subset of developmental disorders (DD) is characterized by disease-specific genome-wide methylation changes. These episignatures inform on the underlying pathogenic mechanisms and can be used to assess the pathogenicity of genomic variants as well as confirm clinical diagnoses. Currently, the detection of these episignature requires the use of indirect methylation profiling methodologies.

Purpose: Severe combined immunodeficiency (SCID) is a set of rare monogenic inherited diseases that together represent the most severe form of the primary immunodeficiency disease phenotype. Preimplantation genetic testing for monogenic defects (PGT-M) is an effective reproductive technology strategy to prevent disease-causing gene mutations from being transmitted to offspring. The aim of this study was to report the use of PGT-M strategy based on karyomapping in four families to avoid the birth of SCID children.
