GALNT2, variants, traits, and what the research shows

GALNT2 - what this gene does

Variants catalogued for GALNT2 are associated primarily with rare disease traits and, in one case, with metabolic function. No mechanistic summaries are yet available for these specific variants, so the characterization below is drawn entirely from the trait labels and magnitude scores (an internal measure combining effect size and evidence strength estimates) in the variant record.

Key takeaways

• Most high-magnitude variants in this gene are flagged under rare disease categories
• One variant, rs619899, carries a metabolic trait association
• Six variants share the highest recorded magnitude score (5.5) in this gene's catalog, all annotated as rare disease
• Multiple independent variants at different magnitude levels reinforce the rare disease signal across the catalog
• These are population-level statistical signals, not individual health predictors

Notable variants

The six highest-magnitude signals - rs138909324, rs142046356, rs1431963909, rs1663959543, rs1665467473, and rs370362368 - each carry a magnitude of 5.5 and are all annotated as rare disease associations. A second tier at magnitude 5.0 adds four more rare disease variants: rs1663960324, rs2102741708, rs2527616593, and rs376870425. The sole metabolic signal among the top-tier variants is rs619899 at magnitude 4.5.

Trait associations

The dominant trait theme across this gene's variant catalog is rare disease, represented by the majority of the 182 variants on file and by all of the highest-magnitude entries. A secondary metabolic association appears via rs619899. Among the magnitude 3.0 tier, several variants - including rs1159628708, rs1170033446, rs1222006987, rs1229327197, rs1307519065, rs1312064338, and rs139591495 - are also annotated as rare disease associations, reinforcing the signal across multiple independent variants at different magnitude levels.

Evidence quality

No prior research summaries are yet available for any of the 182 variants catalogued for this gene, so precise effect sizes, sample sizes, replication status, and source studies cannot be reported here. The clustering of rare disease labels across multiple independent variants at high magnitude is consistent with a genuine signal, but without curated study summaries the mechanistic and clinical context remains uncharacterized in this database. The single metabolic signal (rs619899) is the only variant with a non-rare-disease trait label among the top-tier entries. All trait labels without accompanying study data should be treated as preliminary pointers, not established conclusions.

What this is NOT

These variants represent population-level statistical associations found across large groups of people - they are not deterministic predictors for any individual. This entry does not constitute medical advice, a diagnosis, or a recommendation of any kind.
