Insights
Genetic analysis reveals increased homozygosity and reduced variability in coronary artery disease (CAD) patients compared to controls. This suggests a potential genetic predisposition for developing CAD in both males and females.
Area of Science:
- Genetics
- Cardiology
- Human Physiology
Background:
- Coronary artery disease (CAD) is a multifactorial condition influenced by genetic and environmental factors.
- Understanding genetic predispositions can aid in risk stratification and prevention strategies.
- Morphogenetic variability and homozygosity are potential indicators of genetic health and disease susceptibility.
Purpose of the Study:
- To investigate the association between genetic homozygosity and coronary artery disease (CAD).
- To compare the degree of recessive homozygosity and morphogenetic variability between CAD patients and healthy controls.
- To explore potential gender-specific differences in these genetic markers in relation to CAD.
Main Methods:
- Analyzed morphogenetic variability and homozygosity using the homozygously recessive characteristics (HRC) test in 235 CAD patients and 152 healthy controls.
- Tested 19 specific HRCs to quantify the degree of recessive homozygosity.
- Compared HRC frequencies between CAD patients (with and without diabetes mellitus or hypertension) and control groups, analyzing data separately for males and females.
Main Results:
- CAD patients exhibited a significantly higher frequency of HRCs compared to controls in both males (p < 0.001) and females (p < 0.001).
- This significant difference persisted when comparing controls to CAD patients with diabetes mellitus (DM) and hypertension (HTN).
- No significant difference in HRC frequencies was observed between CAD with DM and CAD with HTN groups.
Conclusions:
- Findings indicate an increased degree of recessive homozygosity and decreased variability in both genders of CAD patients.
- This suggests a potential genetic predisposition contributing to the development of coronary artery disease.
- Genetic factors, specifically homozygosity, may play a significant role in CAD susceptibility.
Abstract:
We analyzed morphogenetic variability and degree of genetic homozygosity in male and female individuals with coronary artery disease (CAD) versus unaffected controls. We have tested 235 CAD patients; 109 were diagnosed also with diabetes mellitus (DM) and 126 with hypertension (HTN). We additionally evaluated 152 healthy individuals without manifested CAD. For the evaluation of the degree of recessive homozygosity, we have performed the homozygously recessive characteristics (HRC) test and tested 19 HRCs. In controls, the frequency of HRC for males was 2.88 ± 1.89, while for females, it was 3.65 ± 1.60. In the CAD group, the frequency of HRC for males was 4.21 ± 1.47, while for females, it was 4.73 ± 1.60. There is significant difference in HRC frequencies between controls and CAD separately for males (p < 0.001) and females (p < 0.001). The same applies between controls and CAD with DM (males: p < 0.001 and females: p = 0.004), and controls and CAD with HTN (males: p < 0.001 and females: p < 0.001). There is no significant difference in HRC frequencies between the group of CAD with DM and the group of CAD with HTN (males: p = 0.952 and females: p = 0.529). Our findings point to the increased degree of recessive homozygosity and decreased variability in both genders of CAD patients versus controls, indicating the potential genetic predisposition for CAD.
