Abstract

An efficient in-vitro regeneration and multiplication protocol was developed to check the effects of different hormonal concentrations through somatic embryogenesis of Pearl millet (Pennisetum glaucum L.). The explants (seeds) of P. glaucum were surface sterilized with different concentrations (30, 50 and 70%) of Sodium hypochlorite to ensure the removal of surface contamination. For the regeneration the explants were inoculated on MS media supplemented with varying concentrations of indole acetic acid (IAA 2 mg/L, 0.75 mg/L, 0.1 mg/L, 0.2 mg/L and 0.3 mg/L) and kinetin (KIN 1.5 mg/L, 0.5 mg/L, 0.5 mg/L, 1 mg/L and 1.5mg/L) respectively. The maximum germination (87.5 %) of explants was obtained by using 70 % Chlorox and minimum germination (62.5 %) of explants was obtained by using 30% Chlorox. The maximum stem length (15.5 cm), roots number (12), roots length (3.96 cm) and leaves length (6.76 cm) was observed on MS medium containing (IAA 2 mg/L and KIN 1.5 mg/L). The maximum leaves number (7) was observed on MS medium containing (IAA 0.75 mg/L and KIN 0.5 mg/L). The minimum stem length (3 cm), roots number (1), roots length (1 cm), leaves number (1) and leaves length (3 cm) was observed on MS medium supplemented with (IAA 0.2 mg/L and KIN 1 mg/L). The maximum Stem length (15.5cm), Roots number (12), Roots length (3.96 cm) and Leaves length (6.76 cm) was observed on MS medium supplemented with (IAA 2 mg/L and KIN 1.5 mg/L) although maximum leaves number was observed on MS medium supplemented with (IAA 0.75 mg/L and KIN 0.5 mg/L). The study revealed an easy and reproducible in-vitro regeneration protocol of pearl millet that can provide an efficient plant regeneration which can be further exploited for transgenic applications

Abstract

Highlights • We found a high asymptomatic rate in vulnerable people with epilepsy. • Enhanced surveillance allows to quickly contain outbreaks. • We report a low rate of COVID-19 morbidity and mortality in a long-term care facility. • Preventative measures allow reducing resident-to-resident and -to-caregiver transmission. • Children and young adults appear to have lower infection rates., In this cohort study, we aim to compare outcomes from coronavirus disease 2019 (COVID-19) in people with severe epilepsy and other co-morbidities living in long-term care facilities which all implemented early preventative measures, but different levels of surveillance. During 25-week observation period (16 March–6 September 2020), we included 404 residents (118 children), and 1643 caregivers. We compare strategies for infection prevention, control, and containment, and related outcomes, across four UK long-term care facilities. Strategies included early on-site enhancement of preventative and infection control measures, early identification and isolation of symptomatic cases, contact tracing, mass surveillance of asymptomatic cases and contacts. We measured infection rate among vulnerable people living in the facilities and their caregivers, with asymptomatic and symptomatic cases, including fatality rate. We report 38 individuals (17 residents) who tested severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive, with outbreaks amongst residents in two facilities. At Chalfont Centre for Epilepsy (CCE), 10/98 residents tested positive: two symptomatic (one died), eight asymptomatic on weekly enhanced surveillance; 2/275 caregivers tested positive: one symptomatic, one asymptomatic. At St Elizabeth’s (STE), 7/146 residents tested positive: four symptomatic (one died), one positive during hospital admission for symptoms unrelated to COVID-19, two asymptomatic on one-off testing of all 146 residents; 106/601 symptomatic caregivers were tested, 13 positive. In addition, during two cycles of systematically testing all asymptomatic carers, four tested positive. At The Meath (TM), 8/80 residents were symptomatic but none tested; 26/250 caregivers were tested, two positive. At Young Epilepsy (YE), 8/80 children were tested, all negative; 22/517 caregivers were tested, one positive. Infection outbreaks in long-term care facilities for vulnerable people with epilepsy can be quickly contained, but only if asymptomatic individuals are identified through enhanced surveillance at resident and caregiver level. We observed a low rate of morbidity and mortality, which confirmed that preventative measures with isolation of suspected and confirmed COVID-19 residents can reduce resident-to-resident and resident-to-caregiver transmission. Children and young adults appear to have lower infection rates. Even in people with epilepsy and multiple co-morbidities, we observed a high percentage of asymptomatic people suggesting that epilepsy-related factors (anti-seizure medications and seizures) do not necessarily lead to poor outcomes.

Abstract

Contains fulltext : 229571.pdf (Publisher’s version ) (Closed access) BACKGROUND: An increasing number of NFKB1 variants are being identified in patients with heterogeneous immunologic phenotypes. OBJECTIVE: To characterize the clinical and cellular phenotype as well as the management of patients with heterozygous NFKB1 mutations. METHODS: In a worldwide collaborative effort, we evaluated 231 individuals harboring 105 distinct heterozygous NFKB1 variants. To provide evidence for pathogenicity, each variant was assessed in silico; in addition, 32 variants were assessed by functional in vitro testing of nuclear factor of kappa light polypeptide gene enhancer in B cells (NF-κB) signaling. RESULTS: We classified 56 of the 105 distinct NFKB1 variants in 157 individuals from 68 unrelated families as pathogenic. Incomplete clinical penetrance (70%) and age-dependent severity of NFKB1-related phenotypes were observed. The phenotype included hypogammaglobulinemia (88.9%), reduced switched memory B cells (60.3%), and respiratory (83%) and gastrointestinal (28.6%) infections, thus characterizing the disorder as primary immunodeficiency. However, the high frequency of autoimmunity (57.4%), lymphoproliferation (52.4%), noninfectious enteropathy (23.1%), opportunistic infections (15.7%), autoinflammation (29.6%), and malignancy (16.8%) identified NF-κB1-related disease as an inborn error of immunity with immune dysregulation, rather than a mere primary immunodeficiency. Current treatment includes immunoglobulin replacement and immunosuppressive agents. CONCLUSIONS: We present a comprehensive clinical overview of the NF-κB1-related phenotype, which includes immunodeficiency, autoimmunity, autoinflammation, and cancer. Because of its multisystem involvement, clinicians from each and every medical discipline need to be made aware of this autosomal-dominant disease. Hematopoietic stem cell transplantation and NF-κB1 pathway-targeted therapeutic strategies should be considered in the future.

Abstract

The Southeast Asian speciesMus (Mus) cookiiRyley 1914 has been previously reported from southern China, Nepal, northeastern and peninsular India, Myanmar, north and central Thailand and Vietnam. A cytochromeb(Cytb) gene analysis revealed the presence ofM. cookiiwhich significantly expands the known western range of this species. However, it is unclear whether theM. cookiipopulation in the Pothwar region represents a historical or recent westward range expansion or, on the contrary, a relictual source population that further experienced an historic eastward range expansion into Southeast Asia.

But despite the fact that Pakistan encompasses an important part of its range, M. m. castaneus populations in Pakistan have not been the subject of intensive genetic and biogeographic studies, except for a very small number of samples included in past studies. We studied genetic variation in M. m. castaneus (CAS) from northern Punjab Province, Pakistan, by using cytochrome b (Cytb) analysis in a sample of 98 individuals. Median-joining network revealed four well differentiated CAS sub-lineages coexisting within a small geographical region; these had previously been thought to have largely non-overlapping geographic distributions. Moreover, haplotypes from Pakistan occupied a central position in the network and all identified global haplotypes were also present in Pakistan. All identified CAS sub-lineages proved to be highly diverse on the basis of haplotype and nucleotide diversity indices. Tajima's D test and Fu's Fs tests of neutrality suggest recent population expansions in all sub-lineages. Expansion times were estimated as 21,760-134,930, 10,800-64,400 and 4950-30,665 ybp using substitution rates of 2.5%, 5% and 11%, respectively. Our results support the hypothesis that northern Punjab Province in Pakistan is the most likely source area for M. m. castaneus, and that the CAS sub-lineages in this region have undergone rapid population expansion events at different time periods, which appear to have benefitted from human-mediated transport, although one of them clearly predates the establishment of human settlements in this region.

Abstract

Mutations in more than 250 genes are implicated in inherited retinal dystrophy; the encoded proteins are involved in a broad spectrum of pathways. The presence of unsolved families after highly parallel sequencing strategies suggests that further genes remain to be identified. Whole-exome and -genome sequencing studies employed here in large cohorts of affected individuals revealed biallelic mutations in ARHGEF18 in three such individuals. ARHGEF18 encodes ARHGEF18, a guanine nucleotide exchange factor that activates RHOA, a small GTPase protein that is a key component of tight junctions and adherens junctions. This biological pathway is known to be important for retinal development and function, as mutation of CRB1, encoding another component, causes retinal dystrophy. The retinal structure in individuals with ARHGEF18 mutations resembled that seen in subjects with CRB1 mutations. Five mutations were found on six alleles in the three individuals: c.808A>G (p.Thr270Ala), c.1617+5G>A (p.Asp540Glyfs ∗ 63), c.1996C>T (p.Arg666 ∗ ), c.2632G>T (p.Glu878 ∗ ), and c.2738_2761del (p.Arg913_Glu920del). Functional tests suggest that each disease genotype might retain some ARHGEF18 activity, such that the phenotype described here is not the consequence of nullizygosity. In particular, the p.Thr270Ala missense variant affects a highly conserved residue in the DBL homology domain, which is required for the interaction and activation of RHOA. Previously, knock-out of Arhgef18 in the medaka fish has been shown to cause larval lethality which is preceded by retinal defects that resemble those seen in zebrafish Crumbs complex knock-outs. The findings described here emphasize the peculiar sensitivity of the retina to perturbations of this pathway, which is highlighted as a target for potential therapeutic strategies.

Abstract

Inherited retinal disease is a common cause of visual impairment and represents a highly heterogeneous group of conditions. Here, we present findings from a cohort of 722 individuals with inherited retinal disease, who have had whole-genome sequencing (n = 605), whole-exome sequencing (n = 72), or both (n = 45) performed, as part of the NIHR-BioResource Rare Diseases research study. We identified pathogenic variants (single-nucleotide variants, indels, or structural variants) for 404/722 (56%) individuals. Whole-genome sequencing gives unprecedented power to detect three categories of pathogenic variants in particular: structural variants, variants in GC-rich regions, which have significantly improved coverage compared to whole-exome sequencing, and variants in non-coding regulatory regions. In addition to previously reported pathogenic regulatory variants, we have identified a previously unreported pathogenic intronic variant in $\textit{CHM}$ in two males with choroideremia. We have also identified 19 genes not previously known to be associated with inherited retinal disease, which harbor biallelic predicted protein-truncating variants in unsolved cases. Whole-genome sequencing is an increasingly important comprehensive method with which to investigate the genetic causes of inherited retinal disease.

Abstract

Mutations in the coiled-coil and DNA-binding domains of STAT1 lead to delayed STAT1 dephosphorylation and subsequently gain-of-function. The associated clinical phenotype is broad and can include chronic mucocutaneous candidiasis (CMC) and/or combined immunodeficiency (CID). We report a case of CMC/CID in a 10-year-old boy due to a novel mutation in the small ubiquitin molecule (SUMO) consensus site at the C-terminal region of STAT1 leading to gain-of-function by impaired sumoylation. Immunodysregulatory features of disease improved after Janus kinase inhibitor (jakinib) treatment. Functional testing after treatment confirmed reversal of the STAT1 hyper-phosphorylation and downstream transcriptional activity. IL-17 and IL-22 production was, however, not restored with jakinib therapy (ruxolitinib), and the patient remained susceptible to opportunistic infection. In conclusion, a mutation in the SUMO consensus site of STAT1 can lead to gain-of-function that is reversible with jakinib treatment. However, full immunocompetence was not restored, suggesting that this treatment strategy might serve well as a bridge to definitive therapy such as hematopoietic stem cell transplant rather than a long-term treatment option.

Abstract

X-linked severe combined immunodeficiency disease (SCID) is caused by mutations in the interleukin (IL)-2 receptor γ (IL2RG) gene and patients usually present with a TBNK SCID phenotype. Nevertheless, a minority of these patients present with a TBNK phenotype, similar to the IL-7R-deficient patients. We report a patient with a novel missense p.Glu297Gly mutation in the IL2RG gene presenting with a leaky TBNK SCID with delayed onset, moderate susceptibility to infections, and nodular regenerative hyperplasia. He presents with preserved STAT5 tyrosine phosphorylation in response to IL-15 stimulation but not in response to IL-2 and IL-7, resulting in the NK phenotype. info:eu-repo/semantics/publishedVersion

The X-linked inhibitor of apoptosis (XIAP) deficiency is a primary immunodeficiency characterized by Epstein-Barr virus (EBV)-driven hemophagocytic lymphohistiocytosis (HLH), splenomegaly, and colitis. Here, we present, for the first time, granulomatous hepatitis and granulomatous and lymphocytic interstitial lung disease (GLILD) as manifestations of XIAP deficiency. We report successful treatment of GLILD in XIAP deficiency with rituximab and azathioprine and discuss the role of XIAP deficiency in immune dysregulation.

Abstract

© 2019 American Society of Human Genetics The occurrence of non-epileptic hyperkinetic movements in the context of developmental epileptic encephalopathies is an increasingly recognized phenomenon. Identification of causative mutations provides an important insight into common pathogenic mechanisms that cause both seizures and abnormal motor control. We report bi-allelic loss-of-function CACNA1B variants in six children from three unrelated families whose affected members present with a complex and progressive neurological syndrome. All affected individuals presented with epileptic encephalopathy, severe neurodevelopmental delay (often with regression), and a hyperkinetic movement disorder. Additional neurological features included postnatal microcephaly and hypotonia. Five children died in childhood or adolescence (mean age of death: 9 years), mainly as a result of secondary respiratory complications. CACNA1B encodes the pore-forming subunit of the pre-synaptic neuronal voltage-gated calcium channel Cav2.2/N-type, crucial for SNARE-mediated neurotransmission, particularly in the early postnatal period. Bi-allelic loss-of-function variants in CACNA1B are predicted to cause disruption of Ca2+ influx, leading to impaired synaptic neurotransmission. The resultant effect on neuronal function is likely to be important in the development of involuntary movements and epilepsy. Overall, our findings provide further evidence for the key role of Cav2.2 in normal human neurodevelopment.

Abstract

Next-generation sequencing has been invaluable in the elucidation of the genetic etiology of many subtypes of intellectual disability in recent years. Here, using exome sequencing and whole-genome sequencing, we identified three de novo truncating mutations in WAS protein family member 1 (WASF1) in five unrelated individuals with moderate to profound intellectual disability with autistic features and seizures. WASF1, also known as WAVE1, is part of the WAVE complex and acts as a mediator between Rac-GTPase and actin to induce actin polymerization. The three mutations connected by Matchmaker Exchange were c.1516C>T (p.Arg506Ter), which occurs in three unrelated individuals, c.1558C>T (p.Gln520Ter), and c.1482delinsGCCAGG (p.Ile494MetfsTer23). All three variants are predicted to partially or fully disrupt the C-terminal actin-binding WCA domain. Functional studies using fibroblast cells from two affected individuals with the c.1516C>T mutation showed a truncated WASF1 and a defect in actin remodeling. This study provides evidence that de novo heterozygous mutations in WASF1 cause a rare form of intellectual disability. ispartof: AMERICAN JOURNAL OF HUMAN GENETICS vol:103 issue:1 pages:144-153 ispartof: location:United States status: published

Abstract

Purpose We aimed to achieve a retrospective molecular diagnosis by applying state-of-the-art genomic sequencing methods to past patients with T-B+NK+ severe combined immunodeficiency (SCID). We included identification of copy number variations (CNVs) by whole exome sequencing (WES) using the CNV calling method ExomeDepth to detect gene alterations for which routine Sanger sequencing analysis is not suitable, such as large heterozygous deletions. Methods Of a total of 12 undiagnosed patients with T-B+NK+ SCID, we analyzed eight probands by WES, using GATK to detect single nucleotide variants (SNVs) and small insertions and deletions (INDELs) and ExomeDepth to detect CNVs. Results We found heterozygous single- or multi-exon deletions in IL7R, a known disease gene for autosomal recessive T-B+NK+ SCID, in four families (seven patients). In three families (five patients), these deletions coexisted with a heterozygous splice site or nonsense mutation elsewhere in the same gene, consistent with compound heterozygosity. In our cohort, about a quarter of T-B+NK+ SCID patients (26%) had such compound heterozygous IL7R deletions. Conclusions We show that heterozygous IL7R exon deletions are common in T-B+NK+ SCID and are detectable by WES. They should be considered if Sanger sequencing fails to detect homozygous or compound heterozygous IL7R SNVs or INDELs.

Abstract

Severe combined immunodeficiency (SCID) is a heterogeneous group of inherited defects involving the development of T- and/or B-lymphocytes. We report a female with atypical severe combined immunodeficiency caused by a novel homozygous mutation at cDNA position 2290 (c.2290C > T) in exon 2 of the RAG1 gene. The patient presented with bronchopneumonia, pyoderma gangrenosum (PG), pancytopenia and splenomegaly. She presented to us with pancytopenia and splenomegaly at the age of 11. Her condition was complicated by PG on left lower ankle at the age of 12. She experienced bronchopneumonia at the age of 15. She was diagnosed with RAG1 deficiency at the age of 16. Her immunological presentation included leucopenia and diminished number of B cells.

Abstract

Defective V(D)J recombination and DNA double-strand break (DSB) repair severely impair the development of T-lymphocytes and B-lymphocytes. Most patients manifest a severe combined immunodeficiency during infancy. We report 2 siblings with combined immunodeficiency (CID) and immunodysregulation caused by compound heterozygous Artemis mutations, including an exon 1–3 deletion generating a null allele, and a missense change (p.T71P). Skin fibroblasts demonstrated normal DSB repair by gamma-H2AX analysis, supporting the predicted hypomorphic nature of the p.T71P allele. In addition to these two patients, 12 patients with Artemis-deficient CID were previously reported. All had significant morbidities including recurrent infections, autoimmunity, EBV-associated lymphoma, and carcinoma despite having hypomorphic mutants with residual Artemis expression, V(D)J recombination or DSB repair capacity. Nine patients underwent stem cell transplant and six survived, while four patients who did not receive transplant died. The progressive nature of immunodeficiency and genomic instability accounts for poor survival, and early HSCT should be considered.

Abstract

With the advent of communication and satellite industry, the need for efficient reflector antenna system has increased tremendously and vast research is undergoing to develop new schemes for analysis and design of reflector antennas more efficiently and accurately. Good sidelobe suppression is required especially in the radar and communication applications from the point of view of reducing mutual unintentional interference as well as deliberate jamming. The principal limitations on the side lobe performance of reflector antennas arise as a consequence of aperture blocking, scattering effects, the feed illumination on the reflector surface, reflector surface errors and feed misalignments. Detailed analysis of these limitations has been carried out in this paper.
