CD8A and vitiligo: For example, Halo Nevi (Leukoderma acquisitum centrifugum of Sutton, OMIM:234300), a dermatological condition in which melanocytes are destroyed by CD8+ cytotoxic T lymphocytes29, has currently no clinical synposis in OMIM and consequently no associated phenotypes in the HPO database, while we identify several phenotypes, including variable depigmentation (MP:0010016), abnormal melanocyte morphology (MP:0002877) and Vitiligo (HP:0001045) as phenotypes, all of which are known to be associated with halo nevi30.
