• ADCK3 mutations with epilepsy, stroke-like episodes and ataxia: a POLG mimic? 

      Hikmat, Omar; Tzoulis, Charalampos; Knappskog, Per; Johansson, Stefan; Boman, Helge; Sztromwasser, Pawel Szymon; Lien, Espen; Brodtkorb, Eylert; Ghezzi, Daniele; Bindoff, Laurence (Peer reviewed; Journal article, 2016-07)
      Background and purpose: Defects of coenzyme Q10 (CoQ10) metabolism cause a variety of disorders ranging from isolated myopathy to multisystem involvement. ADCK3 is one of several genes associated with CoQ10 deficiency that ...
    • GBA2 mutations cause a Marinesco-Sjogren-like syndrome: Genetic and biochemical studies 

      Haugarvoll, Kristoffer; Johansson, Stefan; Rodriguez, Carlos E.; Boman, Helge; Haukanes, Bjørn Ivar; Bruland, Ove; Roque, Francisco; Jonassen, Inge; Blomqvist, Maria; Telstad, Wenche; Månsson, Jan-Eric; Knappskog, Per; Bindoff, Laurence (Peer reviewed; Journal article, 2017-01-04)
      Background: With the advent new sequencing technologies, we now have the tools to understand the phenotypic diversity and the common occurrence of phenocopies. We used these techniques to investigate two Norwegian families ...

      Haugarvoll, Kristoffer; Johansson, Stefan; Tzoulis, Charalampos; Haukanes, Bjørn Ivar; Bredrup, Cecilie; Neckelmann, Gesche; Boman, Helge; Knappskog, Per; Bindoff, Laurence (Peer reviewed; Journal article, 2013-01-03)
      Background: Correct diagnosis is pivotal to understand and treat neurological disease. Herein, we report the diagnostic work-up utilizing exome sequencing and the characterization of clinical features and brain MRI in two ...
    • STUB1 mutations in autosomal recessive ataxias - evidence for mutation-specific clinical heterogeneity 

      Heimdal, Ketil; Sanchez-Guixé, Monica; Aukrust, Ingvild; Bollerslev, Jens; Bruland, Ove; Jablonski, Greg Eigner; Erichsen, Anne Kjersti; Gude, Einar; Koht, Jeanette A.; Erdal, Sigrid; Fiskerstrand, Torunn; Haukanes, Bjørn Ivar; Boman, Helge; Bjørkhaug, Lise; Tallaksen, Chantal M. E.; Knappskog, Per; Johansson, Stefan (Peer reviewed; Journal article, 2014-09-26)
      Background: A subset of hereditary cerebellar ataxias is inherited as autosomal recessive traits (ARCAs). Classification of recessive ataxias due to phenotypic differences in the cerebellum and cerebellar structures is ...
