WebAug 18, 2024 · Homozygous mutation of GRN and lysosome storage disease. While heterozygous mutations of GRN result in FTLD, homozygous GRN mutations lead to a different disease associated with lysosomal dysfunction, namely late onset NCL (Smith et al., 2012; Almeida et al., 2016). NCL is a lysosomal storage disease that is caused by … 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.
