Characterization of PAH Gene Mutations and Analysis of Genotype-Phenotype Correlation in Patients with Phenylalanine Hydroxylase Deficiency from Fujian Province, Southeastern China

Phenylalanine hydroxylase deficiency (PAHD) is the most prevalent inborn error of amino acid metabolism in China, has a complex phenotype with many variants and genotypes among different populations. Here, we analyzed the phenylalanine hydroxylase（ PAH ） gene mutations in a cohort of 93 PAHD patients from Fujian Province. And, the analysis of genotype and phenotype correlation in patients with PAHD was also determined. 44 different pathogenic variants were identified, including five novel variants. The three most prevalent mutations among all patents were p.Arg53His (18.03%), p.Arg241Cys (14.75%), and p.Arg243Gln (7.65%). The frequency of the p.Arg53His variant was the highest in patients with mild hyperphenylalaninemia (MHP), while the frequency of the p.Val399= and p.Arg111Ter variants was the highest in patients with classic phenylketonuria(cPKU). The most abundant genotypes observed in PAHD patients were p.Arg53His/p.Arg243Gln, p.Arg53His/p.IVS4-1G>A, and p.Arg53His/p.Arg241Cysp. As for the genotype-phenotype prediction, the APV/GPV system performed well in predicting the actual phenotype, as the overall consistency rate was 85.71% for PAHD patients. In conclusion, we established a PAH gene mutation spectrum in the PAHD patients in Southeastern China. A quantitative correlation analysis between genotype and phenotype severity is helpful for genetic counseling and management.

GRIN2A Variants Associated With Idiopathic Generalized Epilepsies

Objective: The objective of this study is to explore the role of GRIN2A gene in idiopathic generalized epilepsies and the potential underlying mechanism for phenotypic variation.Methods: Whole-exome sequencing was performed in a cohort of 88 patients with idiopathic generalized epilepsies. Electro-physiological alterations of the recombinant N-methyl-D-aspartate receptors (NMDARs) containing GluN2A mutants were examined using two-electrode voltage-clamp recordings. The alterations of protein expression were detected by immunofluorescence staining and biotinylation. Previous studies reported that epilepsy related GRIN2A missense mutations were reviewed. The correlation among phenotypes, functional alterations, and molecular locations was analyzed.Results: Three novel heterozygous missense GRIN2A mutations (c.1770A &gt; C/p.K590N, c.2636A &gt; G/p.K879R, and c.3199C &gt; T/p.R1067W) were identified in three unrelated cases. Electrophysiological analysis demonstrated R1067W significantly increased the current density of GluN1/GluN2A NMDARs. Immunofluorescence staining indicated GluN2A mutants had abundant distribution in the membrane and cytoplasm. Western blotting showed the ratios of surface and total expression of the three GluN2A-mutants were significantly increased comparing to the wild type. Further analysis on the reported missense mutations demonstrated that mutations with severe gain-of-function were associated with epileptic encephalopathy, while mutations with mild gain of function were associated with mild phenotypes, suggesting a quantitative correlation between gain-of-function and phenotypic severity. The mutations located around transmembrane domains were more frequently associated with severe phenotypes and absence seizure-related mutations were mostly located in carboxyl-terminal domain, suggesting molecular sub-regional effects.Significance: This study revealed GRIN2A gene was potentially a candidate pathogenic gene of idiopathic generalized epilepsies. The functional quantitative correlation and the molecular sub-regional implication of mutations helped in explaining the relatively mild clinical phenotypes and incomplete penetrance associated with GRIN2A variants.

Implementing Total Quality management practices and Employee Performance: Sanita - Lebanon

The aim of the study is find out the impact of applying different total quality management (TQM) practices on the performance of employees in the Lebanese industrial sector. The implementation of total quality management in Lebanese companies is very narrow where few companies work to apply Total Quality Management elements and concepts in its operations. Sanita is a Lebanese company that has applied the principles of total quality management relatively in all of its operations, so it has a large share of its products in the Lebanese market. In this quantitative survey designed study, 160 self-administered questionnaires were distributed for employees working at different career level (Top level management / Middle level management / Supervisor / Operator /technician / other workers) in Sanita main branch (Halat -Lebanon) and Sanita factory (Zouk Mosbeh -Lebanon). The survey concluded various questions related to the dependent variable employee performance and the independent variable related to practices of total quality management (leadership, teamwork, training and education, empowerment, communication). Using the quantitative correlation Pearson test, a strong influence emerged for the implementation of TQM principles on the performance of employees at Sanita and its factories; thus accepting the main alternative hypothesis.

Spectrum Bias and Individual Strengths of SARS-CoV-2 Serological Tests—A Population-Based Evaluation

Antibody testing for determining the SARS-CoV-2 serostatus was rapidly introduced in early 2020 and since then has been gaining special emphasis regarding correlates of protection. With limited access to representative samples with known SARS-CoV-2 infection status during the initial period of test development and validation, spectrum bias has to be considered when moving from a “test establishment setting” to population-based settings, in which antibody testing is currently implemented. To provide insights into the presence and magnitude of spectrum bias and to estimate performance measures of antibody testing in a population-based environment, we compared SARS-CoV-2 neutralization to a battery of serological tests and latent class analyses (LCA) in a subgroup (n = 856) of the larger population based TiKoCo-19 cohort (n = 4185). Regarding spectrum bias, we could proof notable differences in test sensitivities and specificities when moving to a population-based setting, with larger effects visible in earlier registered tests. While in the population-based setting the two Roche ELECSYS anti-SARS-CoV-2 tests outperformed every other test and even LCA regarding sensitivity and specificity in dichotomous testing, they didn’t provide satisfying quantitative correlation with neutralization capacity. In contrast, our in-house anti SARS-CoV-2-Spike receptor binding domain (RBD) IgG-ELISA (enzyme-linked-immunosorbant assay) though inferior in dichotomous testing, provided satisfactory quantitative correlation and may thus represent a better correlate of protection. In summary, all tests, led by the two Roche tests, provided sufficient accuracy for dichotomous identification of neutralizing sera, with increasing spectrum bias visible in earlier registered tests, while the majority of tests, except the RBD-ELISA, didn’t provide satisfactory quantitative correlations.
