IL12B-AS1, variants, traits, and what the research shows

IL12B-AS1 - what this gene does

Based on the available variant data, IL12B-AS1 is a gene with catalogued associations spanning immune function, musculoskeletal health, metabolic processes, and mental health - with immune-related traits appearing most prominently across the variant catalog.

Key takeaways

• Immune-related traits appear most frequently at this locus, with multiple independent variants pointing in the same direction
• The highest-ranked variants also carry associations with musculoskeletal and metabolic traits
• A mental health association appears among the catalogued variants at this locus
• All findings are population-level statistical signals, not individual-level predictors
• Full effect-size and cohort data are not yet available for all variants at this gene

Notable variants

The top-tier signals in this dataset carry magnitude scores of 4.50 and include two immune-associated variants - rs12188300 and rs35990859 - alongside rs4921483, which links to musculoskeletal traits, and rs918519, which carries a metabolic association. rs10076557 and rs114019803 also rank at this top magnitude tier with published entries, though trait-category labels are not available in the current dataset for these two variants. Stepping down to the magnitude-2.80 tier, rs10065906 carries a mental health association, while rs6887695, rs7709212, rs2546890, rs4379175, rs4921482, rs4921492, and rs4921493 all link to immune traits at that tier.

Trait associations

Immune traits account for the largest share of labelled associations at this locus, appearing at both the top magnitude tier (rs12188300, rs35990859) and across seven independent magnitude-2.80 variants (rs2546890, rs4379175, rs4921482, rs4921492, rs4921493, rs6887695, rs7709212). The appearance of the same broad trait category across nine independent variants spanning two magnitude tiers suggests a more robust signal than any single association would imply on its own. Musculoskeletal traits are represented by rs4921483, metabolic traits by rs918519, and mental health by rs10065906 - each currently a single-variant signal in this dataset.

Evidence quality

This gene has 88 total catalogued variants, with 20 carrying prior research summaries. The immune association is the most replicated signal in the available data - appearing across nine independent variants at two distinct magnitude tiers - which lends it more weight compared to the single-variant musculoskeletal, metabolic, and mental health signals. These associations are consistent with GWAS (genome-wide association study - a study that scans many people's genomes for variants statistically associated with a trait) methodology; however, detailed effect sizes, odds ratios, cohort sizes, and multi-cohort replication status are not available within the current summary data for any individual variant. All associations should be treated as preliminary until full summary statistics are published.

What this is NOT

These variants are population-level statistical signals - not deterministic predictors of any trait or condition for any individual person. Nothing presented here constitutes medical advice, a diagnosis, or a clinical recommendation.
