Genome-wide association results for hypersomnia bipolar depression. The Manhattan plot shows the results of susceptible loci relevant to hypersomnia bipolar depression. The chromosomal position is shown along the X-axis, whereas the -log (p value) for each single nucleotide polymorphism is shown along the Y-axis. The horizontal line indicates the p<10-4 significance threshold. The arrows in the figure indicate the position of possible relevant genes above the set threshold.
