Polymorphisms in the PTX1 may not be associated with ischemic stroke susceptibility

Area of Science:

• Genetics
• Neurology
• Epidemiology

Background:

• Ischemic stroke represents a significant global health challenge with high incidence and mortality rates.
• Understanding the genetic underpinnings of ischemic stroke is crucial for potential diagnostic and prognostic advancements.
• The heterogeneity of ischemic stroke necessitates etiological research, including genetic factors.

Purpose of the Study:

• To investigate the association between specific PTX1 gene single nucleotide polymorphisms (SNPs), namely -717A>G and -286C>T>A, and the risk of developing ischemic stroke.
• To contribute to the etiological understanding of ischemic stroke by examining the role of PTX1 gene variations.

Main Methods:

• A meta-analysis approach was employed to estimate the risk of ischemic stroke associated with PTX1 SNPs.
• Summary odds ratios (ORs) were calculated using a fixed-effects model.
• Statistical analysis was performed using STATA software, combining data from 4,604 subjects for SNP -717A>G and 3,093 subjects for SNP -286C>T>A.

Main Results:

• The PTX1 SNP -717A>G showed no statistically significant association with ischemic stroke risk across various comparison models (e.g., GG vs. AA, OR = 1.12; GG + GA vs. AA, OR = 1.04).
• Similarly, the PTX1 SNP -286C>T>A did not demonstrate a significant association with ischemic stroke risk in the meta-analysis (e.g., AA vs. CC, OR = 0.86; AA vs. CC, OR = 0.92).
• Heterogeneity tests (PHet) indicated no significant heterogeneity in the pooled estimates for both SNPs.

Conclusions:

• The findings suggest that the investigated PTX1 gene polymorphisms (-717A>G and -286C>T>A) are unlikely to be associated with an increased predisposition to ischemic stroke.
• Further research may be warranted to explore other genetic factors or environmental influences on ischemic stroke risk.
