313003009 |Rod dystrophy (disorder)| - does this exist as a disorder?

One of our members has advised that an ophthalmologist in their country has stated that the disorder 313003009 |Rod dystrophy (disorder)| as a single entity does not exists and this would be either rod-cone dystrophy or cone-rod dystrophy.
Generally references agreed with this but I found an entry in OMIM of rod dystrophy as manifestation of Adams-Oliver syndrome 2 though rare.

Could you advise please if this can be a distinct disorder or if it should be inactivated.
Many thanks
