"Exploratory analysis of C4B GCN (gene copy numbers)showed positive correlation with neuropil contraction in the cerebellum and superior temporal gyrus among YASZ while AOSZ showed neuropil contraction in the prefrontal and subcortical structures. Thus C4A and C4B GCN are associated with neuropil contraction in regions often associated with schizophrenia and may be neuromaturationally dependent."xsd:string
