B4GALNT3, variants, traits, and what the research shows

B4GALNT3 - what this gene does

Variants catalogued for B4GALNT3 cluster across three broad trait areas - mental health, metabolic, and hormonal. The data on file does not include mechanistic or functional annotation, so this entry describes the trait themes the variants are associated with rather than any underlying biological role.

Key takeaways

• Three highest-signal variants each point to a distinct domain: mental health, metabolic, and hormonal traits.
• All three top-tier variants share the same relative magnitude score, suggesting comparable signal strength across these different areas.
• 138 variants are catalogued for this gene in total; most carry a lower magnitude score and lack specific trait annotations in the current dataset.
• These are population-level statistical associations, not personal health predictions for any individual.
• The evidence is preliminary - replication across larger, independent cohorts is needed before strong conclusions can be drawn.

Notable variants

The three highest-magnitude variants each point to a different trait category. rs11302946 is associated with mental health traits and is the only variant in this gene with a published editorial summary page. rs557639535 is linked to metabolic traits, and rs7955258 is associated with hormonal traits. All three carry an identical magnitude score of 4.50, indicating comparable relative evidence weighting. A further cluster - including rs1035522519, rs1228846392, rs138103066, rs139421625, and rs140633399 among others - each carry a magnitude score of 3.00, but specific trait annotations for these are not available in the current data.

Trait associations

Based on the catalogued variants, this gene appears in research touching three broad areas. Mental health is represented by rs11302946; metabolic traits by rs557639535; and hormonal traits by rs7955258. The remaining catalogued variants do not yet have specific trait labels in this dataset, so the full scope of the gene's trait associations is likely broader than what is currently documented.

Evidence quality

The three top-tier variants each carry a magnitude score of 4.50 - the highest recorded for this gene - but specific effect sizes (such as odds ratios or beta coefficients) and sample sizes are not available in the current dataset. Without those figures, and without confirmed replication across independent cohorts, these signals should be treated as preliminary. Of the 138 total variants on file, only three have trait annotations and only one - rs11302946 - has a published editorial summary. The breadth of trait themes (mental health, metabolic, hormonal) is notable, but each signal currently rests on limited documented evidence.

What this is NOT

These variants are population-level statistical signals from genome-wide association studies (GWAS - studies that scan many people's genomes for variants statistically linked to a trait), not deterministic predictors of any condition for any individual. This encyclopedia entry does not prescribe, diagnose, recommend, or advise any action.
