Figure 4. Correlation of the quantitative trait gene candidate (QTG) SCN4B (voltage-gated sodium channel type IV beta subunit) isoforms.
Scatter plots for three coding variants (NM_001142349, NM_001142348, and NM_174934) of SCN4B, demonstrating a significant negative correlation for only the shortest coding isoform (NM_001142349) for lifetime alcohol consumption in humans.
