WebGRN mutations can cause a movement disorder, including parkinsonism or corticobasal syndrome. GRN mutations can cause Alzheimer’s-like symptoms. Families with a GRN … WebMutations in the GRN gene are a common genetic cause of FTD. Patients with GRN mutations have significantly lower levels of progranulin protein, which is found in lysosomes or “recycling centers” in cells that break down cellular waste and excess proteins. Without enough progranulin, the lysosomes cannot effectively degrade or recycle proteins.
WebFor example, GRN mutations are more common in Northern Italy and the Basque country whilst C9orf72 mutations are particularly common in Nordic countries. For GRN and MAPT there are multiple different mutations in each gene that can occur – so far we recognise more than 170 in GRN and more than 70 in MAPT. 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. #
