Purpose:
Although the relationship between metabolic diseases and primary aldosteronism has been recognized for years, the causal relationship between them remains unclear. Therefore, our study aimed to clarify this uncertainty.
Methods:
Mendelian randomization analysis was performed to explore potential causal links between metabolic diseases and primary aldosteronism. Next, we conducted a mediator analysis to explore the role of plasma proteins in the relationship between metabolic diseases and primary aldosteronism. Finally, phenome-wide association studies (Phe-WAS) were conducted to explore the relationship between primary aldosteronism and other diseases.
Results:
Genetically predicted some metabolic diseases are significantly causally associated with primary aldosteronism, including type 2 diabetes mellitus [odds ratio (OR): 1.20, 95% confidence interval (CI): 1.05-1.37, P = 8.65E-03), fasting insulin levels (OR: 13.66, 95% CI: 4.03-46.28, P = 2.66E-05), BMI (OR: 1.53, 95% CI: 1.09-2.15, P = 1.43E-02), waist-to-hip ratio (OR: 1.82, 95% CI: 1.08-3.06, P = 2.52E-02), waist circumference (OR: 1.77, 95% CI: 1.19-2.64, P = 4.79E-03), and alcohol consumption (OR: 25.82, 95% CI: 2.35-283.28, P = 7.80E-03). The mediator analysis showed that the mediating effect of waist-to-hip ratio via serine hydroxymethyltransferase 1 on primary aldosteronism accounted for 40% (OR: 1.27, 95% CI: 1.03-1.55, P = 2.20E-02). Finally, the Phe-WAS analysis showed that primary aldosteronism might increase the risk of cerebrovascular diseases.
Conclusion:
This study provides genetic evidence suggesting that certain metabolic diseases may increase the risk of primary aldosteronism, highlighting the necessity of enhanced primary aldosteronism screening and prevention in patients with metabolic disorders.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
