What the research says A genome-wide association study (GWAS) of allometric body-shape indices - measures of waist and hip size scaled to account for overall body dimensions, independent of height - was conducted in the UK Biobank using 219,872 women and 186,825 men of white British ancestry, analyzed with BOLT-LMM (a Bayesian linear mixed-model framework that controls for population structure). The study found one to two thirds of its identified loci were novel, with top-ranked genes connected to morphogenesis (tissue formation), organogenesis (organ development), adrenal cell renewal, and cancer-linked pathways. GTEx v11 eQTL data (expression quantitative trait loci - genetic variants that influence how active a gene is) show the alternative allele at rs10859529 is associated with reduced expression of MRPL42 (Mitochondrial Ribosomal Protein L42, a component of the mitochondrial ribosome that participates in making energy-related proteins inside cells) across five tissues GTEx Portal.

Reported associations

  • Allometric body-shape index: rs10859529 at this locus was identified in a GWAS of A Body Shape Index (ABSI), Hip Index (HI), and Waist-to-Hip Index (WHI) in UK Biobank (n = 406,697; 219,872 women and 186,825 men, white British ancestry); the specific index and per-variant effect size are not reported in the available study text.
  • MRPL42 expression (five tissues): the alternative allele is associated with reduced expression in esophagus muscularis (slope -0.18, p = 1.3e-6), aorta (slope -0.16, p = 1.2e-5), subcutaneous adipose tissue (slope -0.14, p = 4.5e-6), thyroid (slope -0.13, p = 2.7e-5), and esophagus mucosa (slope -0.09, p = 1.1e-4) GTEx Portal.

Evidence quality The body-shape GWAS drew on more than 400,000 UK Biobank participants and used BOLT-LMM, a robust Bayesian linear mixed-model framework. The available text does not specify the p-value or per-variant effect size for rs10859529 individually, and the cohort was restricted to white British ancestry, reducing generalizability. The GTEx eQTL data are from GTEx v11 (953 donors, FDR < 0.05) and show a consistent direction of effect across all five tissues (all reduced); however, eQTL associations reflect gene-expression mechanisms and do not directly indicate disease risk or clinical outcomes. The evidence base for this specific variant is preliminary.

Tissue-specific expression effects

  • MRPL42: the alternative allele at this locus is associated with reduced expression of this mitochondrial ribosomal protein in esophagus muscularis, the aorta, subcutaneous adipose tissue, thyroid, and esophagus mucosa; all five signals are in the same direction (reduced expression) GTEx Portal.

Frequently asked questions

What is the SOCS2-AS1 gene?

SOCS2-AS1 is a non-coding RNA gene located near SOCS2 (Suppressor of Cytokine Signaling 2). It does not encode a protein but may help regulate activity of nearby genes. rs10859529 falls within this region.

What body traits is rs10859529 associated with?

rs10859529 was identified in a genome-wide study of allometric body-shape indices, which measure waist and hip size adjusted for overall body dimensions. The study covered more than 400,000 UK Biobank participants, though the specific effect size for this variant is not available in the current data.

What does MRPL42 do and why does its expression matter here?

MRPL42 encodes a component of the mitochondrial ribosome, the structure inside cells that makes proteins needed for energy production. GTEx data show the alternative allele at rs10859529 is associated with reduced MRPL42 activity across five tissues including fat and the aorta. This is a mechanistic finding about gene expression and does not directly indicate a clinical outcome.

Is rs10859529 linked to any disease?

The available study associates rs10859529 with measures of body shape, not with a specific disease diagnosis. No disease association is reported in the provided data.

How strong is the evidence for rs10859529?

The body-shape GWAS used more than 400,000 participants and a robust statistical method, but findings were limited to white British ancestry and the specific p-value and effect size for this variant are not reported in the available text. GTEx eQTL signals are consistent across five tissues but reflect gene expression rather than clinical outcomes. The overall evidence is considered preliminary.
