Several of the most highly enriched GO cellular component terms involved neural functioning, although no terms were sufficiently enriched to pass significance testing after MTC application. Three genes (GRM5, GRM7 and PARK2) were associated with the GO term postsynaptic membrane, four genes (GRM5, GRM7, PARK2 and UNC13C) with synapse, two genes (CHN2 and UNC13C) with synaptosome and two genes (CPLX2, GOSR1) with the SNARE complex, members of which mediate synaptic vesicle fusion.
