Elevated PARP activity has been found in degenerating photoreceptors in a high number of animal models for RP and other inherited retinal degenerations (Arango‐Gonzalez et al. 2014), including in the recently generated RhoI255d autosomal dominant RP mouse (Cao, Dahlen, et al. 2024; Cao, Zhu, et al. 2024). Here, PARP1 is linked to retinitis pigmentosa 1.
