WebHeterozygous mutations in the GRN gene and hexanucleotide repeat expansions in C9orf72 are the two most common genetic causes of Frontotemporal Dementia (FTD) with TDP-43 protein inclusions. The triggers for neurodegeneration in FTD with GRN (FTD-GRN) or C9orf72 (FTD-C9orf72) gene abnormalities are unknown, although evidence from … 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. raj balti https://new-lavie.com
