A:A collection of potential susceptibility genes for depression in different brain regions. SN:substantia nigra;ACC:anterior cingulate cortex;
SC:superior colliculus;CBG:caudate basal ganglia;PFC:prefrontal cortex;NAc:nucleus accumbens;CH:cerebellar hemisphere. B:SMR analy⁃
sis results of depression and eQTL. The horizontal axis represents the chromosomal position of the gene probe,and the vertical axis represents the statis⁃
tical test indicators of the SMR test. C:Collection of potential susceptibility genes for GERD in the gastroesophageal junction,esophageal muscular layer,
esophageal mucosal layer,and peripheral blood(Venn diagram). D:SMR analysis results of GERD and eQTL. E:Collection of potential susceptible
genes for NERD in the gastroesophageal junction,esophageal muscular layer,esophageal mucosal layer,and peripheral blood(Venn diagram). F:SMR
