For instance, the specific disorganized subtype of schizophrenia we observed in this sample, was assocaited with several genes that act in concert with an abnormal GOLGA1 gene.58 Indeed, we previously showed that in the Kechwa sample parkinsonism has a significant association with disorganized and negative symptoms7 and with specific genome-wide genotypes.59 Further studies of the phenotypic and genotypic profiles of this subgroup are warranted to test this hypothesis. Here, GOLGA1 is linked to Parkinsonism.
