Functional evaluation of 16 SCHAD missense variants: Only amino acid substitutions causing congenital hyperinsulinism of infancy lead to loss-of-function phenotypes in vitro
Velasco Pinto, Kelly; St-Louis, Johanna; Hovland, Henrikke N.; Thompson, Nels; Ottesen, Åsta; Choi, Man Hung; Pedersen, Line; Njølstad, Pål Rasmus; Arnesen, Thomas; Fjeld, Karianne; Aukrust, Ingvild; Myklebust, Line Merethe; Molven, Anders (Journal article; Peer reviewed, 2021)Short‐chain 3‐hydroxyacyl‐CoA dehydrogenase (SCHAD), encoded by the HADH gene, is a ubiquitously expressed mitochondrial enzyme involved in fatty acid oxidation. This protein also plays a role in insulin secretion as ... -
The genetic risk factor CEL-HYB1 causes proteotoxicity and chronic pancreatitis in mice
Fjeld, Karianne; Svanbring, Anny Gravdal; Brekke, Ranveig Seim; Alam, Jahedul; Wilhelm, Steven J.; el Jellas, Khadija; Pettersen, Helene Nazmiye; Lin, Jianguo; Solheim, Marie Holm; Steine, Solrun; Johansson, Bente Berg; Njølstad, Pål Rasmus; Verbeke, Caroline Sophie; Xiao, Xunjun; Lowe, Mark E.; Molven, Anders (Journal article; Peer reviewed, 2022)Background & aims: The CEL gene encodes the digestive enzyme carboxyl ester lipase. CEL-HYB1, a hybrid allele of CEL and its adjacent pseudogene CELP, is a genetic variant suggested to increase the risk of chronic pancreatitis ... -
The mucinous domain of pancreatic carboxyl-ester lipase (CEL) contains core 1/core 2 O-glycans that can be modified by ABO blood group determinants
El Jellas, Khadija; Johansson, Bente Berg; Fjeld, Karianne; Antonopoulos, Aristotelis; Immervoll, Heike; Choi, Man Hung; Hoem, Dag; Lowe, Mark E.; Lombardo, Dominique; Njølstad, Pål Rasmus; Dell, Anne; Mas, Eric; Haslam, Stuart M.; Molven, Anders (Peer reviewed; Journal article, 2018)Carboxyl-ester lipase (CEL) is a pancreatic fat-digesting enzyme associated with human disease. Rare mutations in the CEL gene cause a syndrome of pancreatic exocrine and endocrine dysfunction denoted MODY8, whereas a ... -
Pathogenic Carboxyl Ester Lipase (CEL) Variants Interact with the Normal CEL Protein in Pancreatic Cells
Valvatne, Monica Dalva; el Jellas, Khadija; Gravdal, Anny; Njølstad, Pål Rasmus; Molven, Anders; Fjeld, Karianne; Lugea, Aurelia; Pandol, Stephen J; Waldron, Richard T; Lavik, Ida; Johansson, Bente B. (Journal article; Peer reviewed, 2020)Mutations in the gene encoding the digestive enzyme carboxyl ester lipase (CEL) are linked to pancreatic disease. The CEL variant denoted CEL-HYB predisposes to chronic pancreatitis, whereas the CEL-MODY variant causes ... -
The position of single-base deletions in the VNTR sequence of the carboxyl ester lipase (CEL) gene determines proteotoxicity
Svanbring, Anny Gravdal; Xiao, Xunjun; Cnop, Miriam; Jellas, Khadija el; Johansson, Stefan; Njølstad, Pål Rasmus; Lowe, Mark E.; Johansson, Bente Berg; Molven, Anders; Fjeld, Karianne (Journal article; Peer reviewed, 2021)Variable number of tandem repeat (VNTR) sequences in the genome can have functional consequences that contribute to human disease. This is the case for the CEL gene, which is specifically expressed in pancreatic acinar ... -
Two New Mutations in the CEL Gene Causing Diabetes and Hereditary Pancreatitis: How to Correctly Identify MODY8 Cases
Jellas, Khadija el; Dušátková, Petra; Haldorsen, Ingfrid S.; Molnes, Janne; Tjora, Erling; Johansson, Bente Berg; Fjeld, Karianne; Johansson, Stefan; Průhová, Štěpánka; Groop, Leif; Löhr, J. Matthias; Njølstad, Pål Rasmus; Molven, Anders (Journal article; Peer reviewed, 2022)Context Maturity onset diabetes of the young, type 8 (MODY8) is associated with mutations in the CEL gene, which encodes the digestive enzyme carboxyl ester lipase. Several diabetes cases and families have in recent years ...
