The comparison of single cell RNA sequencing from iPSC‐derived RPE cells of 43 patients at the phenotypic end of AMD and of 36 unaffected controls implicated genes at loci definitively associated with disease such as the CFH and ARMS2/HTRA1 loci, and also uncovered new pathogenic loci and pathways.74 Here, CFH is linked to age-related macular degeneration.
