Novel LMF1 nonsense mutation in a patient with severe hypertriglyceridemia
2009
Context: Lipase maturation factor 1 (LMF1) gene is a novel candidate gene in severe hypertriglyceridemia. Lmf1 is involved in the maturation of lipoprotein lipase (LPL) and hepatic lipase in endoplasmic reticulum. To date only one patient with severe hypertriglyceridemia and related disorders was found to be homozygous for a nonsense mutation in LMF1 gene (Y439X).Objective: The objective of the study was to investigate LMF1 gene in hypertriglyceridemic patients in whom mutations in LPL, APOC2, and APOA5 genes had been excluded.Results: The resequencing of LMF1 gene led to the discovery of a novel homozygous nonsense mutation in one patient with severe hypertriglyceridemia and recurrent epis…
PTC124 derivatives as a novel approach to improve the readthrough of premature stop codons in the CFTR gene.
2011
Background Cystic fibrosis (CF) is caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR). Approximately 10% (worldwide) of patients have in-frame nonsense mutations (UAA, UAG or UGA class I mutations) in the CF trans-membrane regulator (CFTR) gene that result in premature stop codons (PTCs) in the messenger RNA (mRNA) generating truncated CFTR protein responsible for a severe CF phenotype. Pharmacological approaches have been proposed to directly overcome PTCs. Ataluren (PTC124) a small molecule that mimics the activity of aminoglycosides has been suggested to allow PTCs readthrough and to partially restore the protein function. However, des…
