Expression of a fusion protein of DISC1 and Boymaw [also called DISC1FP1 (Zhou et al., 2008; Eykelenboom et al., 2012), a potential outcome of a schizophrenia-associated chromosomal translocation] drastically reduces mitochondrial transport and also mitochondrial fusion (Norkett et al., 2016). The gene discussed is DISC1; the disease is schizophrenia.
