rs10771027 (SOX5): Osteoarthritis Genetic Variant

Key takeaways

• rs10771027 near the SOX5 locus (a chromosomal region containing a transcription factor gene involved in skeletal development) was identified in the largest osteoarthritis genetic study to date, spanning nearly 2 million individuals.
• Genetic signals across the study were enriched in embryonic skeletal development pathways, consistent with the locus's role in cartilage and bone formation.
• The study implicated 700 candidate effector genes, with about 10% encoding proteins already targeted by approved drugs.
• 962 independent genetic associations were identified across multiple joint sites including hip, knee, spine, hand, and finger osteoarthritis.
• The dataset was predominantly European (87.3%), which may limit how broadly the findings apply across other ancestry groups.

What the research says A GWAS meta-analysis combining 87 datasets identified rs10771027 near the SOX5 locus among 962 independent osteoarthritis associations across 489,975 cases and 1,472,094 controls (effective sample size 1,470,467), at a study-wide significance threshold of P <= 1.3 x 10^-8. The analysis integrated transcriptome, proteome, and epigenome data from primary joint tissues to implicate 700 effector genes converging on eight biological processes: circadian clock regulation, glial-cell-related processes, and six pathways with established roles in osteoarthritis (TGFbeta, FGF, WNT, BMP, retinoic acid signalling, and extracellular matrix organization); roughly 10% of these effector genes encode proteins targeted by existing approved drugs. Per-variant effect sizes specific to rs10771027 were not reported in the available study text.

Reported associations

• Osteoarthritis (multiple joint phenotypes): rs10771027 was identified among 962 independent associations spanning any-site, hip, knee, combined hip/knee, spine, hand, finger, and thumb osteoarthritis, as well as total hip replacement, total knee replacement, and total joint replacement outcomes in a meta-analysis of up to 1,962,069 individuals; the specific joint phenotype(s) attributed to this variant were not individually detailed in the available study text.

Evidence quality The source study is among the largest osteoarthritis genetic investigations conducted, with an effective sample size of 1,470,467 individuals across 87 datasets and a study-wide significance threshold of P <= 1.3 x 10^-8. Of the 962 identified associations, 513 (53%) were newly reported, mapping to 286 genomic loci of which 176 were newly reported. Most loci (86%) contained a single independent signal, with the remainder encompassing between 2 and 5 independent signals per locus. The ancestry composition covered European (87.3%), East Asian (7.1%), African American (3.1%), South Asian (1.1%), Hispanic (0.9%), and admixed (0.5%) participants, though the European-predominant sample limits transferability of findings to other groups. Functional evidence from transcriptomics, proteomics, and epigenomics of primary joint tissues was integrated to support gene implication beyond simple positional mapping, strengthening confidence in the effector gene candidates. Variant-level statistics including the odds ratio and variance explained for rs10771027 specifically were not included in the available study text.
