Identifying Risk Variants and Genes for Spontaneous Coronary Artery Dissection through Genome-wide Association Meta-analysis
Spontaneous Coronary Artery Dissection (SCAD) is an underdiagnosed cardiac disease that impacts mostly young, healthy, and active women. The disease is known to cause spontaneous dissection of the coronary artery leading to a life-threatening condition. Despite it being a serious disease, there is a lack of knowledge about its genetic basis.
Recent research that involved genome-wide association meta-analysis has helped identify various risk variants and genes associated with SCAD, which can elevate our understanding of the disease and enable better prevention and treatment.
What is Spontaneous Coronary Artery Dissection (SCAD)?
SCAD is a rare and life-threatening condition that causes a spontaneous dissection within the inner layer of arteries from the heart. This condition leads to blockages and interruptions in the blood flow to the heart muscles, which can cause acute cardiac symptoms like heart attacks, abnormal heart rhythms, and even sudden cardiac death.
SCAD is unique because of its disproportionate impact on young, healthy, and mostly active women without traditional risk factors like high blood pressure, cholesterol, obesity, or diabetes.
Genetic Basis of SCAD: Genome-wide Association Meta-analysis
Recent studies have shown that genetic factors could be essential in the onset of SCAD. A combination of genome-wide association meta-analysis and other approaches involving large-scale genetic studies has helped identify multiple genetic variants and genes linked to SCAD.
These genetic studies compared the genomes of individuals who had a history of SCAD with healthy individuals and identified 35 gene regions that could potentially be linked with SCAD. These studies also identified a novel gene named COL15A1 that was found to be associated with SCAD.
The Clinical Implications of Identifying SCAD Risk Variants and Genes
Identifying genetic determinants of SCAD is a crucial step towards better management of the disease in susceptible individuals and high-risk populations. The genome-wide association meta-analysis also found an overlap between genetic variants associated with SCAD and those linked to other cardiovascular disorders, like arterial dissections and connective tissue disorders.
This discovery has helped establish the genetic wellspring for SCAD and provides insight into shared pathways of disease initiation among various vascular diseases. Comprehensive genetic testing to identify SCAD risk variants may potentially help in early diagnosis, prognosis, and management of this life-threatening condition.
Spontaneous Coronary Artery Dissection is a rare, underdiagnosed heart disease mostly affecting young, healthy, and active women. Thanks to recent genetic studies involving genome-wide association meta-analysis, we can now identify various genetic regions and genes potentially linked to SCAD. These insights can help establish the genetic basis of SCAD and allow for better risk assessment and management of the disease.
