Nineteen proteins involved in visual perception and 18 proteins in the retinoid metabolic pathway were DE, and of these one the most upregulated protein was RLBP1, a protein up‐regulated with age in RPE cells31 and associated with a range of retinal dystrophies including non‐syndromic autosomal recessive RP32 and Newfoundland rod‐cone dystrophy33 (Figure 3A, Table S2). The gene discussed is RLBP1; the disease is inherited retinal dystrophy.
