WebMutations in granulin (GRN) have been associated with neurodegenerative diseases, such as frontotemporal lobar degeneration (FTLD) and neuronal ceroid lipofuscinosis (NCL). In Portugal, GRN mutations account for around half of all FTLD cases with known genetic origin. Here, we describe the generation and characterization of three human-induced … WebApr 1, 2011 · Chen-Plotkin et al. (2011) found that R493X was the most common GRN mutation in an international cohort; it was found in 18 (18.6%) of 97 unrelated probands with GRN mutations. All patients with the R493X mutation shared a common haplotype, suggesting a founder effect. #

WebMar 9, 2024 · A common cause of frontotemporal dementia (FTD) are nonsense mutations in the progranulin (GRN) gene. Because nonsense mutations activate the nonsense-mediated RNA decay (NMD) pathway, we sought to inhibit this RNA turnover pathway as a means to increase progranulin levels. Using a knock-in mouse model harboring a …
