What the research says Two large genome-wide association studies of UK Biobank participants form the evidence base for this variant. One examined 19 circulating fatty acid traits across up to 239,268 individuals of European ancestry and five additional ancestry groups, identifying 215 loci for polyunsaturated fatty acid (PUFA)-related traits, 163 loci for monounsaturated fatty acid (MUFA)-related traits, and 119 loci for saturated fatty acid (SFA)-related traits. A second study evaluated the genetic basis of 35 blood and urine laboratory measurements in 363,228 participants, identifying 1,857 associated loci and 3,374 fine-mapped associations, and developed polygenic risk scores for each biomarker.

Reported associations

  • Circulating fatty acid traits: This variant is identified in the context of a GWAS of 19 circulating fatty acid traits, including PUFA-, MUFA-, and SFA-related measures, across UK Biobank participants from six ancestry groups
  • Blood and urine biomarkers: This variant is identified in a study of 35 commonly measured clinical laboratory tests, including lipid, glycemic, kidney function, and liver function measurements, in UK Biobank participants (n=363,228)

Evidence quality The two supporting studies employed large UK Biobank samples (n=239,268 and n=363,228 respectively) and rigorous methods including Bonferroni correction (p < 5 x 10^-9 for genome-wide significance in the biomarker study), statistical fine-mapping to 3,374 associations, and multi-ancestry replication across six ancestry groups in the fatty acid study. However, the provided study excerpts do not include specific association statistics, odds ratios, or beta coefficients for rs117853493 specifically. Without these values, the independent contribution of this variant to the observed trait associations cannot be assessed from the available information. No per-variant replication across independent cohorts is described in the provided text, and the evidence for this specific variant should be treated as preliminary.

Lifestyle considerations No lifestyle considerations on file for this variant.
