Moreover, five RP causative genes (KLHL7, RDH11, CERKL, AIPL1 and USH1G) emerged as already validated targets of five altered miRNAs (hsa‐miR‐1307, hsa‐miR‐3064, hsa‐miR‐4709, hsa‐miR‐3615 and hsa‐miR‐637), suggesting a tight connection between induced oxidative stress and RP development and progression, thanks to the important junction ring represented by regulative functions of miRNAs. Here, CERKL is linked to retinitis pigmentosa 1.
