This gene is associated with a relevant phenotype in OMIM and Gene2Phenotype. Biallic variants in GRN cause Ceroid lipofuscinosis, neuronal, 11, which is characterised by rapidly progressive visual loss due to retinal dystrophy, seizures, cerebellar ataxia, and cerebellar atrophy. There is enough evidence to support a gene-disease association. This gene has been promoted to Amber and should be considered for Green status at the next review.
This gene is also on the Retinal disorders panel (Version 2.71), with the following review:
"Multiple individuals reported with bi-allelic variants and CLN phenotype. Please also note literature regarding retinal abnormalities in those with mono-allelic variants.
