For example, the Mouse Genome Informatics (MGI) database (Blake et al., 2011) annotation of Tg(Prnp-SNCA*A53T)83Vle (a transgenic mouse incorporating a human alpha synuclein variant implicated in Parkinson's Disease) described in Giasson et al. (2002) includes the MPO term “alpha-synuclein inclusion body” (MPO identifier MP:00084931) but uses free text to provide additional detail, such as the fact that the inclusion bodies are observed in the spinal cord, brainstem, cerebellum, and thalamus. Here, MPO is linked to Parkinson disease.
