What the research says This variant is located in the FAM169A-AS1 - RPL27AP5 locus. It was identified as one of 1,857 genome-wide significant loci in a systematic analysis of 35 blood and urine biomarkers measured in 363,228 unrelated UK Biobank participants, using Bonferroni-corrected p < 5 x 10^-9 as the significance threshold for imputed variants. Tissue-specific expression data show that the alternate allele is associated with expression changes in three nearby genes across multiple tissue types, including arterial, immune, and endocrine tissues GTEx Portal.

Reported associations

  • Blood and urine biomarkers: This locus was one of 1,857 genome-wide significant loci identified in a multi-biomarker GWAS spanning 35 clinical laboratory measurements in 363,228 UK Biobank individuals; the precise biomarker trait linked to this locus is not specified in the provided study excerpt.

Evidence quality The primary association evidence comes from a large UK Biobank GWAS (n=363,228 unrelated individuals) spanning five population groups (White British, non-British White, African, South Asian, and East Asian), with meta-analysis conducted across the four largest groups (n=355,891). The study applied Bonferroni correction (p < 5 x 10^-9 for imputed variants) and reported LD Score regression intercepts between 0.999 and 1.137, consistent with well-controlled population stratification. Fine-mapping identified 3,374 associations across all 35 biomarkers, and results were benchmarked against 42 other published cohorts for 25 of the biomarkers. The GTEx eQTL findings are based on 953 donors with FDR < 0.05 as the significance threshold GTEx Portal. Because the specific biomarker trait associated with this locus is not described in the available study text, the phenotypic implications of this variant remain unclear from the provided information.

Tissue-specific expression effects

  • GCNT4: The alternate allele is associated with reduced expression in the aorta (log2 slope -0.85, p=4.1e-9), tibial artery (slope -0.43, p=4.4e-6), and cultured fibroblasts (slope -0.24, p=3.3e-6) GTEx Portal
  • POC5: The alternate allele is associated with increased expression in the spleen (slope +0.70, p=9.0e-5), thyroid (slope +0.45, p=1.6e-5), and cultured fibroblasts (slope +0.34, p=3.0e-6) GTEx Portal
  • ANKDD1B: The alternate allele is associated with increased expression in the aorta (slope +0.57, p=2.0e-5) GTEx Portal
