We now report studies of CSMD1 expression in human postmortem cerebral cortical samples that identify nominally-significant associations between levels of CSMD1 expression and CSMD1 genomic markers, including those that lie near the schizophrenia-associated SNP rs10503253, though these associations do not survive conservative Bonferroni corrections. The gene discussed is CSMD1; the disease is schizophrenia.
