Abstract

Channelopathies are disorders caused by abnormal ion channel function in differentiated excitable tissues. We discovered a unique neurodevelopmental channelopathy resulting from pathogenic variants in SCN3A, a gene encoding the voltage-gated sodium channel NaV1.3. Pathogenic NaV1.3 channels showed altered biophysical properties including increased persistent current. Remarkably, affected individuals showed disrupted folding (polymicrogyria) of the perisylvian cortex of the brain but did not typically exhibit epilepsy; they presented with prominent speech and oral motor dysfunction, implicating SCN3A in prenatal development of human cortical language areas. The development of this disorder parallels SCN3A expression, which we observed to be highest early in fetal cortical development in progenitor cells of the outer subventricular zone and cortical plate neurons and decreased postnatally, when SCN1A (NaV1.1) expression increased. Disrupted cerebral cortical folding and neuronal migration were recapitulated in ferrets expressing the mutant channel, underscoring the unexpected role of SCN3A in progenitor cells and migrating neurons.

Abstract

Phosphotidylinositol (PtdIns) signaling is tightly regulated both spatially and temporally by subcellularly localized PtdIns kinases and phosphatases that dynamically alter downstream signaling events. Joubert syndrome is characterized by a specific midbrain-hindbrain malformation ('molar tooth sign'), variably associated retinal dystrophy, nephronophthisis, liver fibrosis and polydactyly and is included in the newly emerging group of 'ciliopathies'. In individuals with Joubert disease genetically linked to JBTS1, we identified mutations in the INPP5E gene, encoding inositol polyphosphate-5-phosphatase E, which hydrolyzes the 5-phosphate of PtdIns(3,4,5)P3 and PtdIns(4,5)P2. Mutations clustered in the phosphatase domain and impaired 5-phosphatase activity, resulting in altered cellular PtdIns ratios. INPP5E localized to cilia in major organs affected by Joubert syndrome, and mutations promoted premature destabilization of cilia in response to stimulation. These data link PtdIns signaling to the primary cilium, a cellular structure that is becoming increasingly recognized for its role in mediating cell signals and neuronal function.

Abstract

Nephronophthisis (NPH) is an autosomal-recessive ciliopathy representing one of the most frequent causes of kidney failure in childhood characterized by a broad clinical and genetic heterogeneity. Applied to one of the worldwide largest cohorts of patients with NPH, genetic analysis encompassing targeted and whole exome sequencing identified disease-causing variants in 600 patients from 496 families with a detection rate of 71%. Of 788 pathogenic variants, 40 known ciliopathy genes were identified. However, the majority of patients (53%) bore biallelic pathogenic variants in NPHP1. NPH-causing gene alterations affected all ciliary modules defined by structural and/or functional subdomains. Seventy six percent of these patients had progressed to kidney failure, of which 18% had an infantile form (under five years) and harbored variants affecting the Inversin compartment or intraflagellar transport complex A. Forty eight percent of patients showed a juvenile (5-15 years) and 34% a late-onset disease (over 15 years), the latter mostly carrying variants belonging to the Transition Zone module. Furthermore, while more than 85% of patients with an infantile form presented with extra-kidney manifestations, it only concerned half of juvenile and late onset cases. Eye involvement represented a predominant feature, followed by cerebellar hypoplasia and other brain abnormalities, liver and skeletal defects. The phenotypic variability was in a large part associated with mutation types, genes and corresponding ciliary modules with hypomorphic variants in ciliary genes playing a role in early steps of ciliogenesis associated with juvenile-to-late onset NPH forms. Thus, our data confirm a considerable proportion of late-onset NPH suggesting an underdiagnosis in adult chronic kidney disease.

Abstract

Congenital insensitivity to pain with anhidrosis (CIPA) is associated with mutations in the TRKA gene, which encodes a high-affinity tyrosine kinase receptor for nerve growth factor. Eleven new TRKA mutations have been identified in seven families affected with CIPA. The families are from Kuwait, Italy, United Arab Emirates, Spain and Canada. The mutations occur in both the extracellular domain and the intracellular signal-transduction domain of the gene.

45. HAEMORRHAGIC AND ISCHAEMIC STROKE IN CARDIAC ANGIOSARCOMA

Author

Sztriha, Laszlo

Abstract

Cardiac tumours are uncommon with primary malignant cardiac tumours being extremely rare. They are associated with high risk of embolic stoke. We describe a patient with an intracranial haemorrhage and then right MCA infarct who was subsequently diagnosed with a primary cardiac angiosarcoma.A 42 year old female presented with a 3 week history of malaise and breathlessness. Her past medical history was breast carcinoma for which she underwent curative treatment . Examination and vital signs were initially normal. She developed right sided hemiparesis, CT brain showed large left hemispheric intracerebral haemorrhage which required neuro surgical evacuation. There was no aneurysm or other vascular abnormality demonstrated on MR angiogram. MRI brain was performed which showed no evidence of brain metastasis but right MCA territory infarct. A left atrial mass was demonstrated on echocardiogram. Treatment dose heparin was commenced and she underwent surgical resection of the left atrial mass. Tumour histology revealed epithelioid angiosarcoma. She made a very poor neurological recovery and was discharged home with palliative care support.The location of the tumour in the left atrium was unusual for a cardiac angiosarcoma and associated with very high risk of emboli. The mechanism of ICH in this case was not clear with no cerebral metastasis or aneurysm demonstrated on neuroimaging, the patient was too unwell to undergo digital subtraction angiography.Cardiac tumours are a rare but important cause of embolic stroke in young patients and should be considered in the presence of unexplained constitutional or cardiac symptoms.

Abstract

Introduction Transcranial direct current stimulation (tDCS) is a safe and non-invasive brain stimulation technique with the potential to improve upper limb function after stroke. Ipsilesional primary motor cortex (M1) excitability can be increased with anodal tDCS, contralesional M1 excitability can be decreased with cathodal tDCS or both anodal and cathodal tDCS can be used simultaneously on both cortices (bihemispheric). The impact of these different electrode arrangements on the efficacy of tDCS, and whether any of the changes are due to callosal connections between cortices, is unclear. Objectives This study aimed to investigate the effect of tDCS electrode arrangement on motor sequence learning and upper limb function in chronic stroke survivors. Patients and methods 21 stroke survivors (range 3–124 months post-stroke, 34–81 years of age) with upper limb impairment received 20 min of 1 mA tDCS (0.04 mA·cm−2) during performance of a motor sequence learning task which involved movement of a computer mouse with the paretic arm to circular targets on a monitor in a repeating pattern. Four tDCS conditions were studied in a repeated-measures design; (i) anodal to the ipsilesional M1, (ii) cathodal to the contralesional M1, (iii) bihemispheric and (iv) sham. Upper limb function was assessed before and after tDCS, using the Jebsen–Taylor hand function test (JTT). Changes in transcallosal inhibition (TCI) were assessed using transcranial magnetic stimulation (ipsilateral silent period duration). Results There was no effect of tDCS condition on performance of the motor sequence learning task. Performance on the JTT improved significantly after unilateral tDCS (anodal or cathodal) compared to sham (p < 0.05), but not after bihemispheric (Fig. 1). There was no effect on TCI (p > 0.5), and no relationship between changes in TCI and upper limb function. Conclusions Unilateral, but not bihemispheric, tDCS improves upper limb function. The response to tDCS does not appear to be driven by changes in TCI. These results have implications for the use of tDCS for upper limb rehabilitation.
