[Data-modeling] Additional properties to Disease/Physician

[Faye Li]

Hi,

I've added a couple of properties to existing types in the Medicine 
domain on Sandbox and they're ready for review:

1) Type: "Disease or medical condition"
New property: "Associated Genes", with expected type "Gene"
Reverse property on type "Gene" will be "Associated Diseases" (will be 
done once I get a Biology domain admin to help)

For example, Huntington Disease is associated with the hungtingtin gene:

Question: Would it be useful to also add a (unique?) property 
"Cytogenetic Band" (expected type "Cytogenetic Band") to the Disease 
type? And if so, would a reverse property from "Cytogenetic Band" back 
to "Disease" make sense? It would be trivial for me to add both. In the 
case of "Huntington Disease", the property would point to the "Human 
Cytogenetic Band 4p16.3" topic:

2) Type: "Physician"
New property: "Medical Specialty", with expected type "Medical Specialty"
Reverse property on type "Medical Specialty" will be "Physicians with 
this specialty"

For example, Dr. Arne Torkildsen specialized in neurosurgery:
