Genetic correlation analysis between sepsis and hematological traits: Identifying shared genomic regions

Area of Science:

• Genetics
• Hematology
• Infectious Diseases

Background:

• Sepsis is a life-threatening condition caused by infection, leading to significant morbidity and mortality.
• Understanding the genetic basis of sepsis is crucial for improved prevention and treatment.
• Previous research suggests a link between sepsis and hematological traits, but direct genetic correlation analysis is limited.

Purpose of the Study:

• To investigate the global genetic correlation between sepsis and 29 hematological traits.
• To identify specific shared genomic regions between sepsis and hematological traits using local genetic correlation analysis.

Main Methods:

• Systematic evaluation of global genetic correlation between sepsis and a broad range of hematological traits.
• Local genetic correlation analysis to pinpoint shared genomic regions.

Main Results:

• Significant global genetic correlation was found between sepsis and five red blood cell indices.
• Local analyses identified 6-21 shared genomic regions (1.4kb–5.6Mb) between sepsis and seven hematological traits.

Conclusions:

• The study enhances understanding of shared genetic factors between sepsis and blood cell traits.
• Findings offer potential for advancing personalized medicine approaches for sepsis management.
