Gene & Protein in Disease Dopaminergic dysfunction as pre-addiction
Figure 6. The first sub-genomic intelligence (SuGIN) between reward deficiency syndrome (RDS) as the central pre-addiction phenotype and other
pathways as endo-phenotypes. Nature refers to all outer stimuli influencing human cellular and molecular interactions. The human genome may prioritize
key chromosomes—here, we focus on the X and Y chromosomes—which, in turn, could influence autosomal chromosomes and numerous loci and genes.
Within this framework, eight endo-phenotypes are each strongly supported by evidence linking them to RDS at the core. The Genetic Addiction Risk
Severity test, developed by Blum et al., includes alleles from 10 genes. In the figure, arrows represent molecular interactions, while lines refer to the genes
