      We aimed to investigate the epidemiology and natural history of FKRP-related limb-girdle muscular dystrophy R9 (LGMDR9) in Norway. We identified 153 genetically confirmed subjects making the overall prevalence 2.84/100,000, the highest reported figure worldwide. Of the 153 subjects, 134 (88 %) were homozygous for FKRP c.826C>A giving a carrier frequency for this variant of 1/101 in Norway. Clinical ...
    • Identifying sequence variants contributing to hereditary breast and ovarian cancer in BRCA1 and BRCA2 negative breast and ovarian cancer patients 

      Jarhelle, Elisabeth; Stensland, Hilde Monica Frostad Riise; Hansen, Geir Åsmund Myge; Skarsfjord, Siri; Jonsrud, Christoffer; Ingebrigtsen, Monica; Strømsvik, Nina; Van Ghelue, Marijke (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-27)
      Families with breast and ovarian cancer are often tested for disease associated sequence variants in <i>BRCA1</i> and <i>BRCA2</i>. Pathogenic sequence variants (PVs) in these two genes are known to increase breast and ovarian cancer risks in females. However, in most families no PVs are detected in these two genes. Currently, several studies have identified other genes involved in hereditary breast ...
    • Kennedy disease in two sisters with biallelic CAG expansions of the androgen receptor gene 

      Müller, Kai Ivar; Nilssen, Øivind; Nebuchenykh, Maria; Løseth, Sissel; Jonsrud, Christoffer; Hoem, Gry; Van Ghelue, Marijke; Arntzen, Kjell Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-19)
      We present a retrospective 21-year follow-up of two sisters with X-linked biallelic CAG expansions in the androgen receptor (AR) gene causing Kennedy disease. Two sisters inherited CAG expansions from their mother who was a carrier and their father who had Kennedy disease. Genetic testing revealed alleles comprising 43/45, and 43/43 CAG repeats in the younger and older sister, respectively. They ...

      <i>Aim</i> - To investigate the point prevalence of hereditary neuromuscular disorders on January 1, 2020 in Northern Norway.<p> <p><i>Methods</i> - From January 1, 1999, until January 1, 2020, we screened medical and genetic hospital records in Northern Norway for hereditary neuromuscular disorders.<p> <p><i>Results</i> - We identified 542 patients with a hereditary neuromuscular disorder ...
