HDAC9, variants, traits, and what the research shows

HDAC9 - what this gene does

Variants in HDAC9 have been identified across genome-wide association studies (GWAS - studies that scan many people's genomes for variants statistically linked to a trait) as associating with several distinct health domains, including liver-related conditions, cardiovascular traits, musculoskeletal outcomes, and neurological phenotypes.

Key takeaways

• These variants span at least seven trait areas: liver, cardiovascular, musculoskeletal, neurological, immune, cancer, and respiratory
• Three separate liver-associated variants at peak magnitude suggest this may be one of the more consistent signals in this gene's profile
• Two independent variants each point to the cardiovascular and neurological categories, which may indicate replicated signals within those domains
• All listed associations are population-level statistical findings - they describe patterns across large groups, not individual outcomes
• With 224 total variants on file and only 40 carrying research summaries, the full association profile is still emerging

Notable variants

The top-scoring variants (magnitude 4.50) with confirmed trait labels include a liver-associated cluster - rs10236906, rs2520460, and rs551625260 - three independent sites pointing to the same trait area, representing the most numerically concentrated signal in this gene's profile. Cardiovascular associations appear at rs116465573 and rs71524263, and neurological associations at rs1178326 and rs78872508; paired signals within the same trait domain may indicate replication. Single-variant associations also flag musculoskeletal conditions (rs1178121), immune function (rs28465160), cancer (rs35378236), and respiratory traits (rs55744175).

Trait associations

The variant data points to seven distinct trait categories across the top-magnitude tier. Liver-related traits appear the most reinforced numerically - three independent high-magnitude entries share this annotation (rs10236906, rs2520460, rs551625260), a depth not seen in any other single category here. Cardiovascular and neurological traits each carry two-variant signals: rs116465573 and rs71524263 for cardiovascular; rs1178326 and rs78872508 for neurological - multi-variant signals within the same trait area are generally viewed as stronger than single-variant observations. Musculoskeletal (rs1178121), immune (rs28465160), cancer (rs35378236), and respiratory (rs55744175) associations each currently rest on a single high-magnitude variant.

Evidence quality

All variants listed are GWAS-derived statistical associations. Effect sizes (such as odds ratios or beta coefficients) and cohort sample sizes are not available in the current dataset, so the practical magnitude of individual associations cannot be quantified here. Five variants carry published editorial pages - rs10236906, rs10237280, rs116465573, rs1178121, and rs1178326 - indicating greater editorial scrutiny for those entries; the remaining variants are pre-publication. One variant, rs1036752705, carries a lower magnitude score of 3.00, suggesting comparatively weaker or less-replicated evidence relative to the rest of the entries. With 224 total variants on file and only 40 with research summaries, a substantial portion of this gene's association landscape remains uncharacterized.

What this is NOT

These variants are population-level statistical signals from large genetic studies; they are not deterministic predictors of any health outcome for any individual. This content is informational only - we do not prescribe, diagnose, or recommend any course of action.
