can you add a text def for:
name: Pallidal degeneration
xref: UMLS:C0393577 "Pallidal degeneration"
is_a: HP:0007366 ! Atrophy/Degeneration affecting the brainstem
also consider synonyms.
Is this intended to represent any degeneration in the globus pallidus? If so, then is the existing parent class justified?
Currently this phenotype is used once to annotate "pantothenate kinase-associated neurodegeneration", which can affect the brainstem.
