gene -- causes -> phenotype edge from uniprot?

[amykglen]

Sierra was a bit concerned at today's data modeling call to see that the KG2 API returns a uniprot 'causes' edge for the query NCBIGene:351 (APP) -- related_to --> HP:0100543 (Cognitive impairment)

I traced this to the edge with this ID in KG2.10.0pre:

UniProtKB:P05067---biolink:causes---None---None---None---OMIM:104300---identifiers_org_registry:uniprot

(which was returned from the KG2 CI API for this query due to concept subclass reasoning)

does anything seem fishy here? or do we expect to have this sort of edge from uniprot?
