Individual 6 displayed a particularly severe phenotype with high myopia leading to unilateral retinal detachment, potentially caused by coinheritance of a homozygous RP2 variant previously described as pathogenic in a single hemizygous male with retinitis pigmentosa (OMIM 312600)25 but also present in 3 hemizygous males in gnomAD v.2.1.1. This evidence concerns the gene RP2 and retinitis pigmentosa.
