      Svalastoga, Pernille; Kaci, Alba; Molnes, Janne; Solheim, Marie Holm; Johansson, Bente Berg; Krogvold, Lars; Skrivarhaug, Torild; Valen, Eivind; Johansson, Stefan; Molven, Anders; Sagen, Jørn Vegard; Søfteland, Eirik; Bjørkhaug, Lise; Tjora, Erling; Aukrust, Ingvild; Njølstad, Pål Rasmus (Peer reviewed; Journal article, 2023)
      Aims/hypothesis Correctly diagnosing MODY is important, as individuals with this diagnosis can discontinue insulin injections; however, many people are misdiagnosed. We aimed to develop a robust approach for determining ...
    • Functional Analyses of HNF1A-MODY Variants Refine the Interpretation of Identified Sequence Variants 

      Malikova, Jana; Kaci, Alba; Dusatkova, Petra; Aukrust, Ingvild; Torsvik, Janniche; Vesela, Klara; Kankova, Pavla; Njølstad, Pål Rasmus; Pruhova, Stepanka; Bjørkhaug, Lise (Peer reviewed; Journal article, 2020)
      Context While rare variants of the hepatocyte nuclear factor-1 alpha (HNF1A) gene can cause maturity-onset diabetes of the young (HNF1A-MODY), other variants can be risk factors for the development of type 2 diabetes. As ...
    • Functional characterization of HNF4A gene variants identify promoter and cell line specific transactivation effects 

      Kaci, Alba; Solheim, Marie Holm; Silgjerd, Trine; Hjaltadottir, Jorunn; Hornnes, Lorentze Hope; Molnes, Janne; Madsen, Andre Greger; Sjøholt, Gry; Bellanne-Chantelot, Christine; Caswell, Richard; Sagen, Jørn Vegard; Njølstad, Pål Rasmus; Aukrust, Ingvild; Bjørkhaug, Lise (Peer reviewed; Journal article, 2024)
      Hepatocyte nuclear factor-4 alpha (HNF-4A) regulates genes with roles in glucose metabolism and β-cell development. Although pathogenic HNF4A variants are commonly associated with maturity-onset diabetes of the young (MODY1; ...
    • A novel splice-affecting HNF1A variant with large population impact on diabetes in Greenland 

      Thuesen, Anne Cathrine; Stæger, Fredrik Filip; Kaci, Alba; Solheim, Marie Holm; Aukrust, Ingvild; Jørsboe, Emil; Santander, Cindy G.; Andersen, Mette; Li, Zilong; Gilly, Arthur; Stinson, Sara Elizabeth; Gjesing, Anette Prior; Bjerregaard, Peter; Pedersen, Michael Lynge; Larsen, Christina Viskum Lytken; Grarup, Niels; Jørgensen, Marit E.; Zeggini, Eleftheria; Bjørkhaug, Lise; Njølstad, Pål Rasmus; Albrechtsen, Anders; Moltke, Ida; Hansen, Torben (Peer reviewed; Journal article, 2023)
      Background The genetic disease architecture of Inuit includes a large number of common high-impact variants. Identification of such variants contributes to our understanding of the genetic aetiology of diseases and improves ...
    • The E3 SUMO ligase PIASy is a novel interaction partner regulating the activity of diabetes associated hepatocyte nuclear factor-1a 

      Kaci, Alba; Keindl, Magdalena; Solheim, Marie Holm; Njølstad, Pål Rasmus; Bjørkhaug, Lise; Aukrust, Ingvild (Journal article; Peer reviewed, 2018)
      The transcription factor hepatocyte nuclear factor-1α (HNF-1A) is involved in normal pancreas development and function. Rare variants in the HNF1A gene can cause monogenic diabetes, while common variants confer type 2 ...
    • Unsupervised clustering of missense variants in HNF1A using multidimensional functional data aids clinical interpretation 

      Althari, Sara; Najmi, Laeya Abdoli; Bennett, Amanda J.; Aukrust, Ingvild; Rundle, Jana K.; Colclough, Kevin; Molnes, Janne; Kaci, Alba; Nawaz, Sameena; van der Lugt, Timme; Hassanali, Neelam; Mahajan, Anubha; Molven, Anders; Ellard, Sian; McCarthy, Mark I.; Bjørkhaug, Lise; Njølstad, Pål Rasmus; Gloyn, Anna L. (Peer reviewed; Journal article, 2020)
      Exome sequencing in diabetes presents a diagnostic challenge because depending on frequency, functional impact, and genomic and environmental contexts, HNF1A variants can cause maturity-onset diabetes of the young (MODY), ...
