Retinal disorders
Gene: IMPG2Additional evidence for association with retinitis pigmentosa - PMID: 32242237 - Xu et al 2020 - created two independent Impg2 knockout (KO) mouse models using the CRISPR/Cas9 technique. Impg2 ablation in mice recapitulated the retinitis pigmentosa phenotypes of patients, including an attenuated electroretinogram (ERG) response and the progressive degeneration of photoreceptors. The study looks at the effects of Impg2 KO in retinas in detail and provides novel models for mechanistic investigations and development of therapies.Created: 30 Jul 2020, 11:31 a.m. | Last Modified: 30 Jul 2020, 11:33 a.m.
