Transcription factor (PubMed:22194193, PubMed:31691806). Binds to specific sequence motif 5'-TAATTA-3' in regulatory elements of target genes, such as histone demethylase KDM5C (PubMed:22194193, PubMed:31691806). Positively modulates transcription of KDM5C (PubMed:31691806). Activates expression of KDM5C synergistically with histone lysine demethylase PHF8 and perhaps in competition with transcription regulator ZNF711; synergy may be related to enrichment of histone H3K4me3 in regulatory element

Long-Read Genome Sequencing Establishes Biallelic Pathogenic Variants in DNM1 With Distinct Functional Effects as the Cause of Early Infantile Developmental and Epileptic Encephalopathy.
Heterozygous de novo and inherited biallelic pathogenic variants in DNM1 have been reported in association with autosomal dominant (AD) and autosomal recessive (AR) developmental and epileptic encephalopathy, respectively, due to aberrant dynamin function or expression, with each inheritance pattern associated with a different mechanism of disease. We report an instance of DNM1-related early infantile developmental and epileptic encephalopathy due to compound heterozygous pathogenic variants with different functional effects: the de novo dominant negative-associated c.194C>A (p.Thr65Asn), and the maternally inherited loss of function-associated c.850C>T (p.Gln284*). We describe this patient's severe clinical presentation and disease progression as compared to those previously reported with either AD or AR DNM1-related disease. We hypothesize about the interactions and outcomes of the two variants at the molecular level following review of in vitro and in vivo functional data and demonstrate the utility of long-read genome sequencing for phasing the variants and confirming this individual's molecular diagnosis.
Clinical insights into dental care for siblings with Jamuar syndrome: a rare genetic dual case report.
Jamuar syndrome, caused by a mutation in a protein-coding gene called the UGDH (UDP-glucose 6-dehydrogenase), is an extremely rare genetic condition that presents with craniofacial dysmorphisms, developmental delay and epileptic encephalopathy. Despite its rarity, a proper diagnosis and management depends on the knowledge of its oral clinical presentation and genetic foundation to ensure thorough oral rehabilitation. The clinical characteristics of Jamuar disease described in this report are of two siblings, 20- and 13-year-old sisters, who both displayed a constellation of symptoms consistent with the disease. Both the children displayed unique physical phenotypes, such as developmental delays and craniofacial dysmorphism, along with distinct physical impairments and intellectual difficulties. The older sibling presented with early onset chronic localized periodontitis and comprehensive dental treatment was carried out under general anaesthesia, while the younger sibling had generalized gingivitis and an enamel fracture with upper left central incisor. Multiple affected siblings and the rare occurrence of Jamuar syndrome emphasize the hereditary and familial basis of the condition. This instance emphasizes how crucial it is to take uncommon genetic abnormalities into account when making a differential diagnosis for children who exhibit complicated clinical presentations. Future treatment approaches for Jamuar syndrome may be guided by more research that clarifies its pathophysiology, and the formulation of an oral care plan. The discovery that these siblings have Jamuar syndrome adds to the expanding amount of information about this uncommon condition and highlights the need for dental practitioners to be more cognizant of it. Genetic testing and family history analysis are essential for diagnosing and understanding the implications of rare genetic conditions like Jamuar syndrome.
Nav1.2 channel mutations preventing fast inactivation lead to SCN2A encephalopathy.
SCN2A gene-related early-infantile developmental and epileptic encephalopathy (EI-DEE) is a rare and severe disorder that manifests in early infancy. SCN2A mutations affecting the fast inactivation gating mechanism can result in altered voltage dependence and incomplete inactivation of the encoded neuronal Nav1.2 channel and lead to abnormal neuronal excitability. In this study, we evaluated clinical data of seven missense Nav1.2 variants associated with DEE and performed molecular dynamics simulations, patch-clamp electrophysiology and dynamic clamp real-time neuronal modelling to elucidate the molecular and neuron-scale phenotypic consequences of the mutations. The N1662D mutation almost completely prevented fast inactivation without affecting activation. The comparison of wild-type and N1662D channel structures suggested that the ambifunctional hydrogen bond formation between residues N1662 and Q1494 is essential for fast inactivation. Fast inactivation could also be prevented with engineered Q1494A or Q1494L Nav1.2 channel variants, whereas Q1494E or Q149K variants resulted in incomplete inactivation and persistent current. Molecular dynamics simulations revealed a reduced affinity of the hydrophobic IFM-motif to its receptor site with N1662D and Q1494L variants relative to wild-type. These results demonstrate that the interactions between N1662 and Q1494 underpin the stability and the orientation of the inactivation gate and are essential for the development of fast inactivation. Six DEE-associated Nav1.2 variants, with mutations mapped to channel segments known to be implicated in fast inactivation were also evaluated. Remarkably, the L1657P variant also prevented fast inactivation and produced biophysical characteristics that were similar to those of N1662D, whereas the M1501V, M1501T, F1651C, P1658S and A1659V variants resulted in biophysical properties that were consistent with gain-of-function and enhanced action potential firing of hybrid neurons in dynamic action potential clamp experiments. Paradoxically, low densities of N1662D or L1657P currents potentiated action potential firing, whereas increased densities resulted in sustained depolarization. Our results provide novel structural insights into the molecular mechanism of Nav1.2 channel fast inactivation and inform treatment strategies for SCN2A-related EI-DEE. The contribution of non-inactivating Nav1.2 channels to neuronal excitability may constitute a distinct cellular mechanism in the pathogenesis of SCN2A-related DEE.
Mixed functional consequences of the N651D GRIA3 variant: a case of early-onset developmental and epileptic encephalopathy with parkinsonism.
Rare variants in GRIA3, the gene encoding the GluA3 subunit of amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type glutamate receptors (AMPARs), are associated with defects in early brain development. Disease-causing variants are generally categorised as either loss of function (LoF) or gain of function (GoF) that appear to be linked to different symptoms. Here, we reported a de novo variant (N651D) that has mixed LoF and GoF in a female patient with a devastating developmental and epileptic encephalopathy, parkinsonism and cortical malformation. N651D is located in the M3 segment, which forms the filter pore of AMPAR tetramers. Interestingly, functional assays revealed that glutamate induced no currents in GluA3_N651D homomeric receptors, likely indicating an LoF effect. However, when co-expressed with the GluA2 subunit, the GluA2/A3_N651D heteromeric receptors showed slower deactivation and desensitisation curves, along with elevated non-desensitising steady-state currents, features typically observed in GoF variants. We speculate that variants with mixed LoF and GoF effects may lead to a more devastating phenotype compared with variants with GoF effects only.
A De Novo Splicing Mutation of STXBP1 in Epileptic Encephalopathy Associated with Hypomyelinating Leukodystrophy.
Deleterious variations in STXBP1 are responsible for early infantile epileptic encephalopathy type 4 (EIEE4, OMIM # 612164) because of its dysfunction in the central nervous system. The clinical spectrum of the neurodevelopmental delays associated with STXBP1 aberrations is collectively defined as STXBP1 encephalopathy (STXBP1-E), the conspicuous features of which are highlighted by early-onset epileptic seizures without structural brain anomalies. A girl was first diagnosed with unexplained disorders of movement and cognition, which later developed into STXBP1-E with unexpected leukoaraiosis and late onset of seizures. Genetic screening and molecular tests alongside neurological examinations were employed to investigate the genetic etiology and establish the diagnosis. A heterozygous mutation of c.37+2dupT at the STXBP1 splice site was identified as the pathogenic cause in the affected girl. The de novo mutation (DNM) did not result in any truncated proteins but immediately triggered mRNA degradation by nonsense-mediated mRNA decay (NMD), which led to the haploinsufficiency of STXBP1. The patient showed atypical phenotypes characterized by hypomyelinating leukodystrophy, and late onset of epileptic seizures, which had never previously been delineated in STXBP1-E. These findings strongly indicated that the haploinsufficiency of STXBP1 could also exhibit divergent clinical phenotypes because of the genetic heterogeneity in the subset of encephalopathies.
