We found, after correcting for tumor volume and location, correlations between the expression level of CD3 or IDH-1 and psychomotor speed; IDH-1, BDNF, ATRX, CK2Beta, GAT-3, NLGN3, SRF, or EAAT1 and memory performance, and P-STAT5b, NLGN3, CK2Beta, or IDH-1 and executive functioning. The gene discussed is NLGN3; the disease is neoplasm.
