The frequent variant A57F in the gene in patients from Russia has Finno-Ugric Mari origin.

Introduction: GNE-myopathy is a distal myopathy with adult-onset and initial involvement of anterior leg compartment. A founder effect has been demonstrated for some patients from several large cohorts in different countries.

Methods: In this study, we investigated the allele frequency of the c.

Challenging Diagnosis of a Patient with Two Novel Variants in the Gene.

We report a case of -associated autosomal recessive spinocerebellar ataxia (SCAR8) presenting with a complex multisystemic phenotype, including highly elevated creatine kinase levels and lower-leg muscle atrophy. In addition to identifying two novel pathogenic variants in the gene, whole-exome sequencing revealed three variants of uncertain significance in the gene. Electromyography and muscle magnetic resonance imaging indicated a neurogenic pattern of muscle involvement.

Asymmetric scapuloperoneal phenotype of -related distal myopathy: case series.

Recent research has sparked a discussion on the spectrum of diseases linked to the gene associated with amyotrophic lateral sclerosis and distal myopathy with vocal cord and pharyngeal weakness (VCPDM). To date, fewer than 50 cases of VCPDM have been reported in the literature. We aim to build upon the work of previous researchers by gathering additional information about VCPDM.

Highly Sensitive and Reliable Detection of EGFR Exon 19 Deletions by Droplet Digital Polymerase Chain Reaction.

Background: Analysis of EGFR mutations is becoming a routine clinical practice but the optimal EGFR mutation testing method is still to be determined.

Methods: We determined the nucleotide sequence of deletions located in exon 19 of the EGFR gene in lung tumor samples of patients residing in different regions of Russia (153 tumor DNA specimens), using Sanger sequencing. We developed a droplet digital polymerase chain reaction assay capable of detecting all common EGFR deletions in exon 19.

Simulation of high-energy radiation belt electron fluxes using NARMAX-VERB coupled codes.

This study presents a fusion of data-driven and physics-driven methodologies of energetic electron flux forecasting in the outer radiation belt. Data-driven NARMAX (Nonlinear AutoRegressive Moving Averages with eXogenous inputs) model predictions for geosynchronous orbit fluxes have been used as an outer boundary condition to drive the physics-based Versatile Electron Radiation Belt (VERB) code, to simulate energetic electron fluxes in the outer radiation belt environment. The coupled system has been tested for three extended time periods totalling several weeks of observations.
