A case of childhood hyperekplexia due to a novel nonsense variant in the GLRA1 gene.

Medicine2026 Jan 23

Hyperekplexia is a rare hereditary neurological disorder characterized by an exaggerated startle response and generalized rigidity. It is frequently misdiagnosed as epilepsy, leading to unnecessary treatment. We report a case of mild hyperekplexia caused by a novel GLRA1 mutation, highlighting the diagnostic value of genetic testing in atypical presentations. An 18-month-old girl presented with recurrent episodes of vacant staring and limb rigidity triggered by sudden sounds or tactile stimuli over the past 2 months. She had a history of 3 febrile seizures but normal development. Physical examination revealed hypersensitivity to external stimuli, but the nose-tap test was negative. Routine metabolic studies, brain magnetic resonance imaging, and electroencephalogram were normal. Whole-exome sequencing identified a de novo heterozygous nonsense variant c.593G > A (p.Trp198Ter) in the GLRA1 gene, confirming the diagnosis of hyperekplexia. Given the confirmed diagnosis and the mild nature of the symptoms, the previously prescribed antiepileptic drug (levetiracetam) was discontinued. Clonazepam was not initiated due to the mild severity of the condition. At the 8-month follow-up, the patient remained seizure-free with minimal non-epileptic stimulus-induced symptoms. Her growth and psychomotor development were normal. This case expands the phenotypic spectrum of GLRA1-related hyperekplexia to include mild phenotypes with a negative nose-tap test. It underscores the critical role of whole-exome sequencing in distinguishing hyperekplexia from epilepsy, thereby avoiding inappropriate antiepileptic therapy. Asparagine synthetase deficiency (ASD) mainly presents as a triad of congenital microcephaly, severe developmental delay, and axial hypotonia followed by spastic quadriplegia. Low cerebrospinal fluid asparagine concentration can help the clinician in differentiating this disorder from others. In most individuals with ASD, apnea, excessive irritability, and seizures occur soon after birth. Affected individuals typically do not acquire any developmental milestones. Spastic quadriplegia can lead to severe contractures of the limbs and neurogenic scoliosis. Feeding difficulties (gastroesophageal reflux disease, frequent vomiting, swallowing dysfunction, and gastroesophageal incoordination) are a significant problem in most affected individuals. A majority have cortical blindness. Brain MRI findings are nonspecific but may include generalized atrophy and simplified gyral pattern. The diagnosis of ASD is established in a proband with suggestive findings and biallelic pathogenic variants in ASNS identified by molecular genetic testing. Treatment of manifestations: Supportive developmental therapies; standard treatment for seizures; antispastic medication (baclofen, tizanidine) and/or Botox® injection for spasticity; clonazepam for hyperekplexia; treatment of scoliosis per orthopedist; feeding therapy and/or nasogastric or gastrostomy tube to support nutrition; pharmacologic treatment for gastroesophageal reflux disease; standard treatment for constipation; low vision services as needed; mechanical ventilation may be required for apnea; regular immunizations to prevent life-threatening infections; hearing aids as needed for hearing loss; transitional plan to adult care; social work and family support. Surveillance: At each visit, evaluation of developmental progress and growth; assessment for progression of spasticity and contractures; assessment for new neurologic manifestations; physical medicine and occupational and physical therapy assessment of mobility and self-help skills; assessment for scoliosis; measurement of growth parameters; assessment of nutritional status and safety of oral intake; assessment for constipation; and assessment for evidence of aspiration and respiratory insufficiency. Measurement of serum total protein, albumin, and prealbumin every six months. Annual ophthalmologic evaluation. EEG if there are concerns for new-onset seizure activity or progression of seizures. Audiologic evaluation if there are concerns for hearing loss. ASD is inherited in an autosomal recessive manner. If both parents are known to be heterozygous for an ASNS pathogenic variant, each sib of an affected individual has at conception a 25% chance of being affected, a 50% chance of being an asymptomatic carrier, and a 25% chance of being unaffected and not a carrier. Once the ASNS pathogenic variants have been identified in an affected family member, carrier testing for at-risk relatives and prenatal/preimplantation genetic testing are possible.

A Novel Variant in GLRA1 Associated With Emotional Stimulus-Sensitive Hemichoreic Movements.

American journal of medical genetics. Part A2026 Mar

We present the case of a 61-year-old woman with late-onset hyperkinetic movement disorder, characterized by involuntary, choreiform movements predominantly affecting the right limbs. Symptoms began at age 60 and were exacerbated by emotional stress. Neurological and neurocognitive evaluations were unremarkable, and extensive diagnostic workup, including Magnetic Resonance Imaging (MRI), Electroencephalogram (EEG), Positron Emission Tomography with Fluorodeoxyglucose (FDG-PET) and genetic testing for common movement disorders, was largely negative. Notably, a heterozygous pathogenic variant (c.736C>T; p.Arg246Trp) in the GLRA1 gene was identified via exome sequencing. This gene encodes a glycine receptor subunit associated with Hyperekplexia (HPX), a rare neurometabolic disorder typically presenting in infancy with exaggerated startle responses. Although our patient did not show a classic HPX phenotype, the clinical picture included emotionally triggered motor symptoms and a positive response to clonazepam, a hallmark of HPX treatment. Clonazepam monotherapy at low doses led to sustained symptom control, while other treatments were less effective. Family history revealed similar late-onset symptoms in the patient's father, though undocumented. This case expands the phenotypic spectrum of HPX and suggests that atypical presentations may be misclassified as functional neurological disorders. It underscores the importance of genetic evaluation in unexplained adult-onset movement disorders and raises the possibility of underrecognized late-onset HPX variants in clinical practice.

A New GlyT2 Variant Associated with Hyperekplexia.

International journal of molecular sciences2025 Jul 14

Hyperekplexia (OMIM 149400), a sensorimotor syndrome of perinatal clinical relevance, causes newborns to display an energic startle reflex in response to certain trivial stimuli. This condition can be lethal due to apnea episodes. The disease is caused by a blockade of glycinergic neurotransmission. Glycinergic interneurons preserve their identity by the activity of the surface glycine transporter GlyT2, which supplies glycine to presynaptic terminals to maintain glycine content in synaptic vesicles. Loss-of-function mutations in the GlyT2 gene (SLC6A5) cause a presynaptic form of human hyperekplexia. Here, we describe a new GlyT2 variant found in an infantile patient diagnosed with hyperekplexia. A missense mutation in the open reading frame of the GlyT2 gene inherited in homozygosity caused the substitution G449E in a residue highly conserved across the phylogenetic scale. The sequences of the glycine receptor genes GLRA1 and GLRB did not show abnormalities. We expressed the recombinant GlyT2 variant in heterologous cells and analyzed its pathogenic mechanism. The transporter was totally inactive, behaving as a bona fide loss-of-function mutant. Furthermore, the mutation promoted the abnormal insertion of the protein into the membrane, leading to its large incorporation into lipid rafts. However, there was no apparent alteration of wild-type trafficking upon mutant coexpression, as the mutant was prematurely degraded from the endoplasmic reticulum. Rescue with chemical chaperones was not possible for this mutant. Proteomics demonstrated that the expression of the mutant induced the unfolded protein response and interfered with raft-dependent processes. Therefore, the new variant causes a loss of function regarding GlyT2 activity but a gain of function as a cell proteostasis disturber.

Motor phenotyping in a Greek cohort of patients with neonatal and infantile onset developmental and epileptic encephalopathy.

European journal of paediatric neurology : EJPN : official journal of the European Paediatric Neurology Society2025 Mar

Developmental and epileptic encephalopathy (DEE) includes diseases where there is developmental impairment related to both the underlying etiology independent of epileptiform activity and the epileptic encephalopathy. Patients often present with movement disorders (MD). This study aims to delineate the motor phenotype in a cohort of patients with DEE. Retrospective review of 82 patients with DEE. MD type and distribution were documented and when available, video recordings were reviewed. Patients were classified into five etiological groups: 30.5 % had a likely genetic diagnosis, 29.3 % a confirmed genetic diagnosis, 18.3 % an inborn error of metabolism (IEM), 14.6 % an acquired brain lesion, and 7.3 % a brain dysplasia. Hyperkinetic MDs were present in 85.4 % of patients, including dystonia (48.8 %), stereotypies (22.0 %), chorea (20.7 %), hyperekplexia (15.9 %), tremor (14.6 %), and myoclonus (6.1 %). Parkinsonism was observed in 11 % of patients, ataxia in 8.5 % and multiple MDs in 50 %. Paroxysmal episodes of MD exacerbation occurred in 6 patients, and transient MD in 8. Dystonia was most frequent in patients with acquired brain lesions (p = 0.003). Parkinsonism was more frequent in patients with brain dysplasias and IEM (p = 0.043). This study confirms the high frequency of hyperkinetic and combined MD in DEE, and identifies characteristic MDs in conditions such SCN8A, FOXG1 and ARX related DEE, as well as ataxia and tremor in STXBP1, SCN1A, MTRFR, KCTD7 and 15q111-13 deletion. Novel observations, include the occurrence of paroxysmal dyskinetic exacerbations in FOXG1, axial stereotypies in KCNQ2, hyperekplexia in cortical dysplasia and Parkinsonism in ECHS1 with DEE.

Rafiq Syndrome: Old Variant in MAN1B1 Gene and Some New Phenotypic Features.

Iranian journal of child neurology2025

Rafiq syndrome is a congenital disorder of glycosylation type II that develops due to mutations in the Mannosidase Alpha Class 1B Member 1 (MAN1B1) gene encoding α 1,2-mannosidase. In the literature, 45 patients have been reported to date. This study presents a patient with some phenotypic traits that differ from previously reported patients with Rafiq syndrome.Since the patient was not diagnosed despite detailed examinations, whole exome sequencing was performed. The patientss' homozygous c.1000 C>T (p.Arg334Cys) pathogenic variant was detected in the MAN1B1 gene (NM_016219.5), which was consistent with Rafiq syndrome. Our patient's clinical findings were mainly similar to those of previously reported patients. However, our patient had feeding difficulty that started to improve after the fifth month and persistent hyperekplexia . Feeding difficulty and hyperekplexia concomitant to MAN1B1 gene mutation are reported for the first time. More extensive case series are needed to understand whether these findings are part of the syndrome or incidental comorbid conditions.
