Subject: Preserve gene symbol case when used as an identifer.

Genes with varying casing (e.g., Shh, SHH) result in
`string->identifier` capitalizing the first letter by default.  This
creates inconsistencies in gene symbols, leading to different
predicates and objects for the same entity, introducing errors.
