Figure 2From: Association study of OPRM1 polymorphisms with Schizophrenia in Han Chinese population Linkage disequilibrium (LD) plot of 4 OPRM1 SNPs in SZ cases and controls. There was only one LD block in OPRM1 gene. (The numbers in the squares are D’X 100. Squares are colored bright red if the D’value is high (i.e. LD is strong) and the confidence in the value of D’is high as well).Back to article page
