Aicardi-Goutieres syndrome (AGS) is a genetic encephalopathy whose clinical features mimic those of acquired in utero viral infection. AGS exhibits locus heterogeneity, with mutations identified in genes encoding the 3'-->5' exonuclease TREX1 and the three subunits of the RNASEH2 endonuclease complex. To define the molecular spectrum of AGS, we performed(More)
Accurate interpretation of electroretinograms (ERGs) requires knowledge of effects of axial myopia on ERG responses. Our purpose was to derive expected changes of ERG responses according to axial length, to stimulus conditions that conform to the International Society for Clinical Electrophysiology of Vision (ISCEV) Standard for Electroretinography. ERGs(More)
AIM To describe the clinical spectrum of achiasmia, a congenital disorder of reduced relative decussation at the optic chiasm. METHODS A retrospective case note and patient review of nine children (four boys). Achiasmia was defined by the combination of a characteristic asymmetry of the monocular visual evoked potential (VEP) response to flash and(More)
Coats plus is a highly pleiotropic disorder particularly affecting the eye, brain, bone and gastrointestinal tract. Here, we show that Coats plus results from mutations in CTC1, encoding conserved telomere maintenance component 1, a member of the mammalian homolog of the yeast heterotrimeric CST telomeric capping complex. Consistent with the observation of(More)
Craniosynostosis, the premature fusion of cranial sutures, may be associated with raised intracranial pressure (ICP) with or without a reduced intracranial volume. Regardless of the aetiology, raised ICP may result in optic neuropathy, the timely detection of which can prevent further visual deterioration. Raised ICP is usually treated with craniofacial(More)
Disease-causing mutations affecting either one of the transcription factor genes, PITX2 or FOXC1, have been previously identified in patients with Axenfeld-Rieger syndrome (AR). We identified a family who segregate novel mutations in both PITX2 (p.Ser233Leu) and FOXC1 (c.609delC). The most severely affected individual, who presented with an atypical(More)
OBJECTIVE Changing trends in multiple sclerosis (MS) epidemiology may first be apparent in the childhood population affected with first onset acquired demyelinating syndromes (ADSs). We aimed to determine the incidence, clinical, investigative and magnetic resonance imaging (MRI) features of childhood central nervous system ADSs in the British Isles for the(More)
PURPOSE Stuve-Wiedemann syndrome is a rare condition consisting of bone dysplasia, hypotony, and dysautonomia with ocular and neuropathic features. We present the ocular findings and visual outcome in 4 patients (2 siblings, 1 related cousin, and 1 unrelated patient) with this syndrome. METHODS A retrospective case series review. Clinical notes of 4(More)
The classification system of congenital corneal opacification (CCO) may be better considered from a perspective of pathogenesis, surgical intervention, and prognosis. The author feels that CCO is best considered as being primary and secondary. Primary CCO includes corneal dystrophies and choristomas presenting at birth. Secondary CCO may be best considered(More)
asymmetry and an arcuate scotoma. During a 3 month follow-up period the intraocular pressure did not differ significantly between the two eyes. She subsequently developed a left RAPD. This was felt to be inconsistent with the previous clinical signs. Unilateral left optic nerve dysfunction was diagnosed and the possibility of optic nerve compression was(More)
