Turner’s syndrome is characterized by the partial or complete absence of one of the sex chromosomes in women in association with one or more clinical exposures. Molecular techniques such as polymerase chain reaction (PCR) are useful when it comes to complementing the genetic approach, as they present greater sensitivity in recognizing mosaicism. Considering the high percentage of mosaicism and the possible clinical impact of the presence of Y chromosome in these patients, we proposed in this s...

Alport syndrome is an inherited disease of collagen IV leading to progressive glomerular sclerosis associated with variable degrees of proteinuria and haematuria, sensorineural deafness and ocular abnormalities. Here we describe a novel mutation involving the COL4A5 gene leading to X-linked Alport syndrome (XLAS) in a Singhalese family of six children born to nonconsanguineous parents of Sri Lankan origin. The eldest 19-year-old male was found to have microscopic haematuria and proteinuria. His ...

As COVID-19 has spread from its origin in Wuhan, China, into a global pandemic, there has been a number of efforts to understand the mutations and clusters of genetic lineages of the SARS-CoV-2 virus. The high mutation rate and rapid spread makes this analysis capable of tracking chains of infections as well as putting individual sequences in context. So far, phylogenetic analysis methods have recently found a broader application in this regard. Here we demonstrate that Principal Component Analy...

Splicing is a part of mRNA maturation process when exons of pre-mRNA transcript are joined in multiple ways. In case of alternative splicing, some exons may be excluded from the final mRNA, and the resulting ensemble of mRNAs creates different protein isoforms, allowing multiple proteins to be coded by a single gene. To detect new events of alternative splicing in human blood cells, we used RNA-seq technology. A pipeline based on Python "Scikit-Learn" library was developed for efficient splicing...

Serotonin and its receptors, including the 5-Hydroxytryptamine Receptor 2A encoded by the HTR2A gene, are important for learning and memory in animals and humans.Polymorphic variation in the HTR2A gene, which encodes the 5-HT2Aserotonin receptor, has previously been shown to associate with some memory traits,in particular effecting delayed verbal memory. In the current study we have examined the HTR2A His452Tyr (H452Y) substitution for association in a cohort of healthy individuals whose memory ...

Introduction: Haemophilia A (HA) is the most common X-linked recessive genetic disease caused by mutations in the gene coding for coagulation factor VIII (FVIII) resulting in spontaneous bleeding. Aim: The aim of our study is to provide additional information about the genetic causes of HA describing the correlation between the observed mutations and the clinical phenotype in a cohort of 52 patients suffering from HA to different degrees. Methods: First we performed a search of inversion 22 ...

The availability of a representative Gene Ontology (GO) database is a prerequisite for a successful functional genomics study. Using the online Blast2GO tool we constructed a GO database of Aspergillus flvus, a plant and human pathogen. Of the predicted total 13,485 A. flvus genes 8,987 were annotated with GO terms. The mean GO level was 5.64. Using a low stringency setting of a sequence cut-off number of 10 and a node score of 20, we obtained 1,177 GO terms associated with biological process, 3...

The clinical implementation of new target enrichment methods and next-generation sequencing (NGS) technology has rapidly transformed genetic testing. Diagnostic labs can now offer a wide variety of large comprehensive multi-gene panels or even full exome sequencing to help clinicians diagnose and treat patients. The unmatched sensitivity, accuracy and throughput of NGS compared to traditional Sanger sequencing make it an ideal technology not only for panels but also high volume single gene assay...

Aim: Immune mechanisms of Cytomegalovirus (CMV) infection suggest a possible relationship between CMV with development of acute graft rejection. Current immune suppression impairs antiviral specifi T-cell immunity in solid organ transplantation. Inhibitory/ activating NK receptor bindings activated by self HLA antigens confront allogeneic cells that lack a ligand for specifi receptor. KIR ligand incompatibility caused due to presence/absence of KIR receptor in recipient and corresponding HLA lig...

Objective: To describe the effect of Hydroxyurea (HU) treatment in Omani Sickle Cell Disease (SCD) patients with different beta-globin gene cluster haplotypes. Materials and methods: A total of 52 cases treated with HU were enrolled in this study. Response to the drug was compared between patients with and without the XmnI polymorphism in the different betaglobin gene cluster haplotypes. We have classified our cohort into three categories: good responders to HU for those patients who had no cr...

This study presents data on the carrier frequencies of IVS1+1 G>A mutation in GJB2 gene, causing by autosomal recessive form of deafness among various ethno-geographical groups of Yakut population and in a random sample of the Yakuts. 350 DNA samples of hearing individuals from various ethno-geographical groups of Yakut population: Central (n=60), Vilyui (n=60), Northern (n=60) and random samples of Yakuts (n=170) were obtained from the DNA Bank of the Department of Molecular Genetics of Yakut R...
