Promises and pitfalls of whole-exome sequencing exemplified by a nephrotic syndrome family.

Mol Genet Genomics

January 2020

Laboratory of Human Molecular Genetics, Center for Molecular Biology and Genetic Engineering (CBMEG), State University of Campinas, UNICAMP, Caixa Postal 6010, 13083-875, Campinas, SP, Brazil.

High-throughput techniques such as whole-exome sequencing (WES) show promise for the identification of candidate genes that underlie Mendelian diseases such as nephrotic syndrome (NS). These techniques have enabled the identification of a proportion of the approximately 54 genes associated with NS. However, the main pitfall of using WES in clinical and research practice is the identification of multiple variants, which hampers interpretation during downstream analysis.

Nuclear receptor subfamily 5 group A member 1 (NR5A1), also named steroidogenic factor 1, is an essential transcription factor that regulates a number of target genes crucial for normal reproductive physiology and endocrine function. It is encoded by NR5A1 gene and is expressed in high doses mainly in steroidogenic tissues, where it controls several steps of adrenal and gonadal development. NR5A1 mutations are associated with a wide phenotypic spectrum of disorders/differences of sex development (DSD), a group of conditions in which development of chromosomal, gonadal, or anatomic sex is atypical.

In the rhizosphere, the soil bacteria and the plants are closely related, with the plant-associated microbiota playing an important role in promoting plant growth under both normal and stress conditions. In this study, the cultivable bacteria in the sugarcane rhizosphere under different levels of drought stress were characterized and screened for plant growth activities. The results suggested that the microbial community associated with the sugarcane rhizosphere was strongly affected by drought, but some important genera of bacteria such as Arthrobacter, Pseudomonas, Microbacterium, and Bacillus remained present during the entire experiment, indicating the adaptability of these organisms and their importance in the rhizosphere community.

Unlabelled: Although sickle cell anemia results from homozygosity for a single mutation at position 7 of the β-globin chain, the clinical aspects of this condition are very heterogeneous. Complications include leg ulcers, which have a negative impact on patients’ quality of life and are related to the severity of the disease. Nevertheless, the complex pathogenesis of this complication has yet to be elucidated.

Article Synopsis
  • Changes in the placenta's structure and molecules due to environmental factors may help us understand diseases better.
  • A unique case study involving a patient with sickle cell anemia revealed different pregnancy outcomes linked to severe preeclampsia and a mostly uncomplicated pregnancy, suggesting a connection between sickle cell anemia and preeclampsia.
  • The study indicates that mechanisms like copper response and triglyceride metabolism might play significant roles in preeclampsia, urging more research with larger sample sizes to further investigate these findings.

Background: The purpose of this study was to screen juvenile open angle glaucoma (JOAG) patients from Brazil for variants within the MYOC and CYP1B1 genes.

Material And Methods: In this study, we evaluated the coding regions of MYOC and CYP1B1 genes in 100 non-related patients with JOAG and 200 controls through Sanger sequencing. We also tested the most frequent single nucleotide variants of CYP1B1 for association with JOAG.

Understanding relationships between genes responsible for enzymatic hydrolysis of cellulose and synergistic reactions is fundamental for improving biomass biodegradation technologies. To reveal synergistic reactions, the transcriptome, exoproteome, and enzymatic activities of extracts from Trichoderma harzianum, Trichoderma reesei and Trichoderma atroviride under biodegradation conditions were examined. This work revealed co-regulatory networks across carbohydrate-active enzyme (CAZy) genes and secreted proteins in extracts.

Article Synopsis
  • Large-scale genome-wide association studies have identified genetic variants associated with primary open-angle glaucoma (POAG), specifically rs4236601 (CAV1/CAV2) and rs2157719 (CDKN2B-AS1).
  • This study aimed to assess the impact of these variants on POAG incidence in a Brazilian Southeastern population through a case-control analysis of 557 individuals.
  • The findings indicated that the heterozygous genotype of rs2157719 was more common in controls, suggesting its protective role, while no significant association was found for rs4236601, supporting the relevance of rs2157719 in POAG risk.

Steroidogenic factor-1 (SF1), encoded by the NR5A1 gene, is a key regulator of steroidogenesis and reproductive development. NR5A1 mutations described in 46,XY patients with disorders of sex development (DSD) can be associated with a range of conditions of phenotypes; however, the genotype-phenotype correlation remains elusive in many cases. In the present study, we describe the impact of five NR5A1 variants (three novel: p.

Background: Trichoderma harzianum is used in biotechnology applications due to its ability to produce powerful enzymes for the conversion of lignocellulosic substrates into soluble sugars. Active enzymes involved in carbohydrate metabolism are defined as carbohydrate-active enzymes (CAZymes), and the most abundant family in the CAZy database is the glycoside hydrolases. The enzymes of this family play a fundamental role in the decomposition of plant biomass.
