Journal ArticleDOI
Idiopathic Torsion Dystonia: Assignment of a Gene to Chromosome 18p in a German Family With Adult Onset, Autosomal Dominant Inheritance and Purely Focal Distribution
TL;DR: A linkage study in a large pedigree with seven definitely affected, six possibly affected and 16 phenotypically unaffected family members assigns an ITD gene for the common focal form with a maximal lod score of 3.17 to the region telomeric of D18S1153 on chromosome 18p.
Journal Article
Localization of the candidate gene D-amino acid oxidase outside the refined I-cM region of spinocerebellar ataxia 2.
Suzana Gispert,Astrid Lunkes,N. Santos,G. Orozco,Ha-Hao D,Tim Ratzlaff,Jorge Aguiar,Torrens I,L. Heredero,Alexis Brice +9 more
TL;DR: Although SCA2 in most patients cannot be distinguished from other spinocerebellar ataxias by clinical criteria, in some patients it exhibits a particular phenotype with early neuropathy/late slow saccades and late myoclonus, and complete allelic association within the Holguin population was established with the microsatellite D12S105.
Journal ArticleDOI
Mutation Detection in Machado-Joseph Disease Using Repeat Expansion Detection
K. Lindblad,Astrid Lunkes,Patrícia Maciel,Patrícia Maciel,Giovanni Stevanin,Cecilia Zander,Thomas Klockgether,Tim Ratzlaff,Alexis Brice,Guy A. Rouleau,Thomas J. Hudson,Georg Auburger,Martin Schalling +12 more
TL;DR: It is concluded that RED is a reliable method for analyzing expanded repeat sequences in the genome in disorders where linkage is complicated by phenotyping problems in gradually developing adult-onset disorders, as in the non-SCA1–5 family examined.
Journal ArticleDOI
Expanding the scope of an eConsult service: acceptability and feasibility of an optometry-ophthalmology pilot project.
Clare Liddy,Sheena Guglani,Tim Ratzlaff,Robert L. Campbell,Lacey Cranston,Andrea Miville,Martin ten Hove,Erin Keely +7 more
TL;DR: The eConsult Vision Pilot Project as discussed by the authors provides an opportunity for patients to get access to specialty advice by connecting optometrists to ophthalmologists on an econsult service.
Journal ArticleDOI
Changes in Scleral Thickness Following Repeated Anti-vascular Endothelial Growth Factor Injections
Yao Wang,FRCSC; Wei Sim,MA; Patrick Wang,Rachel Y. Oh,Tim Ratzlaff,Jacob Rullo,Sanjay Sharma +6 more
TL;DR: Compared to injection naive eyes, multiple intravitreal injections at the repeated sCleral quadrant results in scleral thinning.
