Abstract: Abstract. Purpose. The mediating roles of tolerance to workplace incivility between ethical leadership and intention to sabotage was investigated in Jordan. The study relied on social learning theory (Bandura, 1977; 1986), reinforcement theory (Skinner, 1938), and conservation of resource theory (Hobfoll, 1988). Methodology. A quantitative method with survey questionnaires were distributed to 376 employees in different universities, public and private, in northern Jordan to obtain data. The following variables were part of the self-administered survey developed for the purposes of this study: “ethical leadership” (10-item scale); “tolerance to workplace incivility” (8-item scale); “the intention to sabotage” (8-item scale). Data were analyzed with SPSS and structural equation modeling with AMOS. Findings. A significant and direct negative relationship was found between ethical leadership and employees’ intention to sabotage in Jordan. Also, a significant and direct positive effect was found between tolerance to workplace incivility and employees’ intention to sabotage, which indicates that tolerance to incivility increases intention to sabotage in Jordan. Further, it was found that tolerance to workplace incivility partially mediates the relationship between ethical leadership and employees’ intention to sabotage in Jordan. Value of results. This paper improves the understanding of workplaces in Jordanian universities and facilitates the creation of healthier work environments. The findings also contribute to several fields of organizational research, such as: human resources management, organizational development, and organizational behavior. The findings have many theoretical and practical implications, which were discussed.

Abstract: This study aims to investigate the impact of Human Resource Management Practices (HRMP) on improving Employee Performance (EP). The study is accomplished by hypothesizing the impact of HRMP on EP, additionally, this impact is theorized to be mediated through job satisfaction. Employee engagement is also taken into account because of the potential moderating effect it has within the theorized model. Data was collected from 480 questionnaires which were distributed among commercial banks' workers in Jordan and were analyzed using structural equation modeling techniques (SEM), path analysis, and confirmatory factor analysis (CFA). Analysis of a moment structures (AMOS) software version 24 was applied to complete our analysis. The results show that HRMP had a positive impact on EP, as well as job satisfaction and its components (job stability and job enrichment). The mediating role of job satisfaction (enrichment and stability) was discovered. Finally, employee engagement emerged as a moderating variable linking HRMP and EP. The findings of this study show the importance of the role played by job satisfaction and employee engagement in achieving human resources performance goals. Future analysis is recommended to gain deeper insight into the relationship between HRMP, job satisfaction, worker training, and performance appraisal

Research Title: Skewed X-chromosome inactivation in unsolved neurodevelopmental disease cases can guide re-evaluation for X-linked genes.

Abstract: Despite major advances in genome technology and analysis, >50% of patients with a neurodevelopmental disorder (NDD) remain undiagnosed after extensive evaluation. A point in case is our clinically heterogeneous cohort of NDD patients that remained undiagnosed after FRAXA testing, chromosomal microarray analysis and trio exome sequencing (ES). In this study, we explored the frequency of non-random X chromosome inactivation (XCI) in the mothers of male patients and affected females, the rationale being that skewed XCI might be masking previously discarded genetic variants found on the X chromosome. A multiplex fluorescent PCR-based assay was used to analyse the pattern of XCI after digestion with HhaI methylation-sensitive restriction enzyme. In families with skewed XCI, we re-evaluated trio-based ES and identified pathogenic variants and a deletion on the X chromosome. Linkage analysis and RT-PCR were used to further study the inactive X chromosome allele, and Xdrop long-DNA technology was used to define chromosome deletion boundaries. We found skewed XCI (>90%) in 16/186 (8.6%) mothers of NDD males and in 12/90 (13.3%) NDD females, far beyond the expected rate of XCI in the normal population (3.6%, OR = 4.10; OR = 2.51). By re-analyzing ES and clinical data, we solved 7/28 cases (25%) with skewed XCI, identifying variants in KDM5C, PDZD4, PHF6, TAF1, OTUD5 and ZMYM3, and a deletion in ATRX. We conclude that XCI profiling is a simple assay that targets a subgroup of patients that can benefit from re-evaluation of X-linked variants, thus improving the diagnostic yield in NDD patients and identifying new X-linked disorders.

Research Title: 2. A reverse genetics and genomics approach to gene paralog function and disease: Myokymia and the juxtaparanode.

Abstract: The leucine-rich glioma-inactivated (LGI) family consists of four highly conserved paralogous genes, LGI1-4, that are highly expressed in mammalian central and/or peripheral nervous systems. LGI1 antibodies are detected in subjects with autoimmune limbic encephalitis and peripheral nerve hyperexcitability syndromes (PNHSs) such as Isaacs and Morvan syndromes. Pathogenic variations of LGI1 and LGI4 are associated with neurological disorders as disease traits including familial temporal lobe epilepsy and neurogenic arthrogryposis multiplex congenita 1 with myelin defects, respectively. No human disease has been reported associated with either LGI2 or LGI3. We implemented exome sequencing and family-based genomics to identify individuals with deleterious variants in LGI3 and utilized GeneMatcher to connect practitioners and researchers worldwide to investigate the clinical and electrophysiological phenotype in affected subjects. We also generated Lgi3-null mice and performed peripheral nerve dissection and immunohistochemistry to examine the juxtaparanode LGI3 microarchitecture. As a result, we identified 16 individuals from eight unrelated families with loss-of-function (LoF) bi-allelic variants in LGI3. Deep phenotypic characterization showed LGI3 LoF causes a potentially clinically recognizable PNHS trait characterized by global developmental delay, intellectual disability, distal deformities with diminished reflexes, visible facial myokymia, and distinctive electromyographic features suggestive of motor nerve instability. Lgi3-null mice showed reduced and mis-localized Kv1 channel complexes in myelinated peripheral axons. Our data demonstrate bi-allelic LoF variants in LGI3 cause a clinically distinguishable disease trait of PNHS, most likely caused by disturbed Kv1 channel distribution in the absence of LGI3.

Research Title: Human COQ4 Deficiency: Delineating the clinical, metabolic and neuroimaging phenotypes

Author: Tawfiq Froukh, Published Year: 2022

Faculty: Science

Abstract: Background: Human coenzyme Q4 (COQ4) is essential for coenzyme Q10 (CoQ10) biosynthesis. Pathogenic variants in COQ4 cause childhood-onset neurodegeneration. We aimed to delineate the clinical spectrum and the cellular consequences of COQ4 deficiency. Methods: Clinical course and neuroradiological findings in a large cohort of paediatric patients with COQ4 deficiency were analysed. Functional studies in patient-derived cell lines were performed. Results: We characterised 44 individuals from 36 families with COQ4 deficiency (16 newly described). A total of 23 different variants were identified, including four novel variants in COQ4. Correlation analyses of clinical and neuroimaging findings revealed three disease patterns: type 1: early-onset phenotype with neonatal brain anomalies and epileptic encephalopathy; type 2: intermediate phenotype with distinct stroke-like lesions; and type 3: moderate phenotype with non-specific brain pathology and a stable disease course. The functional relevance of COQ4 variants was supported by in vitro studies using patient-derived fibroblast lines. Experiments revealed significantly decreased COQ4 protein levels, reduced levels of cellular CoQ10 and elevated levels of the metabolic intermediate 6-demethoxyubiquinone. Conclusion: Our study describes the heterogeneous clinical presentation of COQ4 deficiency and identifies phenotypic subtypes. Cell-based studies support the pathogenic characteristics of COQ4 variants. Due to the insufficient clinical response to oral CoQ10 supplementation, alternative treatment strategies are warranted.
