The R90W mutation is associated with cone-rod dystrophy in humans, though expression of Hsap\CRXR90W.Scer\UAS.T:Zzzz\FLAG is not stated to specifically model this retinopathy in D. melanogaster.
Hsap\CRXR90W.UAS.Tag:FLAG/Scer\GAL4oc.1.6 is a suppressor of rhabdomere phenotype of ocuvi
Hsap\CRXR90W.UAS.Tag:FLAG/Scer\GAL4oc.1.6 is a suppressor of ommatidium phenotype of ocuvi
Expression of Hsap\CRXR90W.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4oc.1.6 largely rescues rhabdomere and ommatidial morphology in ocuvi flies.
