Heterozygous variants in the RHO gene encoding for rhodopsin (RHO), a visual 348 amino acid G‐protein‐coupled receptor, are the leading cause of autosomal dominant retinitis pigmentosa (RP), which is a group of inherited retinal degenerative diseases due to loss of rod/cone photoreceptors [195]. Here, RHO is linked to autosomal dominant retinitis pigmentosa.
