Clinical Report: Link Between CTLA-4 Genetic Variants and T1D in Kurds
Overview
This study investigates the association of CTLA-4 genetic variants with type 1 diabetes (T1D) susceptibility in the Kurdish population. The A>G (rs231775) variant was associated with T1D, while the -318 C>T (rs5742909) polymorphism showed no significant differences.
Background
Type 1 diabetes is a complex autoimmune disease influenced by genetic and environmental factors. This study focuses on the Kurdish population and the role of CTLA-4 variants in T1D susceptibility.

A>G (rs231775)
Associated
P = 0.0188
-318 C>T (rs5742909)
No significant differences
N/A
GG genotype prevalence in anti-GAD positive
77.78% vs. 22.22%
P = 0.28
Key Findings
The A>G (rs231775) variant is associated with T1D susceptibility in the Kurdish population.
The G allele frequency was higher in T1D patients (36.5%, P = 0.0188).
The -318 C>T (rs5742909) polymorphism showed no significant differences between T1D patients and controls.
The GG genotype of the +49A/G polymorphism was more prevalent in anti-GAD positive patients (77.78% vs. 22.22%).
CTLA-4 mRNA expression was non-significantly elevated in T1D patients compared to controls (p = 0.1239).
Clinical Implications
The findings suggest that genetic screening for the CTLA-4 A>G variant may help identify individuals at higher risk for T1D in the Kurdish population. Understanding these genetic associations can inform future research and potential therapeutic strategies.
Conclusion
The study reports an association of the CTLA-4 A>G variant with T1D susceptibility in the Kurdish population, while the -318 C>T polymorphism did not show significant differences.
