Regulatory variant RS4151680 in 5Q31.3 confers major depressive disorder risk by regulating SMC3 binding and PCDHA8 expression

Key Points

• Major depressive disorder risk is influenced by regulatory variant RS4151680, which alters SMC3 binding.
• Evidence shows that altered SMC3 interaction affects PCDHA8 gene expression crucial for mood regulation.
• The analysis highlights connections between genetic variants and the physiological mechanisms of depression.
• Findings suggest that targeting these genetic pathways could lead to novel therapeutic strategies.
