A pilot genome-wide association study of ischemic heart disease with co-occurring arterial hypertension in a Kazakh cohort.

A pilot GWAS of ischemic heart disease with hypertension in Kazakh individuals identified ZFHX3 as the strongest suggestive locus but found no variants reaching genome-wide significance.

• Why it matters: This research addresses the underrepresentation of Central Asian populations in GWAS of ischemic heart disease, which limits understanding of genetic risk factors in this group.
• What they did: The study genotyped 470 Kazakh individuals (240 cases, 230 controls) using the Illumina array, performed association testing with logistic regression, and conducted post-imputation and secondary analyses to identify candidate loci.
• The result: While no SNPs achieved Bonferroni significance, the locus near ZFHX3 showed the strongest association signals, highlighting the need for larger cohorts and replication to confirm its role in this population.
