EXOC4, variants, traits, and what the research shows

EXOC4 - what this gene does

EXOC4 is a human gene whose variants have been studied in connection with neurological conditions, mental health traits, rare disease, cancer, and cardiovascular phenotypes. The available data does not provide enough mechanistic detail to characterize this gene's biological function beyond the trait themes the variants reveal.

Key takeaways

• Eleven variants in this gene are linked to neurological traits - the dominant pattern in the data.
• The highest-priority variant carries a rare disease association at the largest recorded magnitude.
• Three separate variants connect this gene to mental health conditions.
• Cancer and cardiovascular associations also appear, each once at the top evidence tier.
• All of these are population-level statistical signals, not individual health predictions.

Notable variants

The variant with the highest recorded magnitude is rs730882233 (magnitude 5.00), associated with a rare disease trait - the only variant in this gene reaching that priority tier. Among the magnitude-4.50 signals, the neurological-linked rs10281827 and rs11977339 are the two neurological variants with published research pages. Mental health associations at the same tier include rs10954428, rs6949760, and rs6978272. The cancer-linked rs141588684 and the cardiovascular-linked rs6975094 complete the cross-trait picture in the top-tier data.

Trait associations

Neurological traits account for the largest share of catalogued associations - eleven variants in total, including rs10281827, rs11977339, rs12707093, rs1424580, rs2346449, rs2971963, rs35284403, rs4728302, rs6949831, rs6950324, and rs6972284. The recurrence of neurological signals across eleven independent variants is the most consistent pattern in the data. Mental health traits appear in three variants - rs10954428, rs6949760, and rs6978272 - adding a second domain of nervous-system-adjacent associations. The rare-disease signal from rs730882233 carries the highest individual magnitude in the dataset. Cancer (rs141588684) and cardiovascular (rs6975094) associations each appear once at the top evidence tier.

Evidence quality

The dataset for this gene comprises 184 catalogued variants, 24 of which carry prior research summaries; three top-tier variants - rs10281827, rs11977339, and rs10954428 - have published editorial pages. Most associations are consistent with GWAS (genome-wide association study - a study design that scans large numbers of genomes for statistical links to a trait) discovery signals, which reflect population-level patterns and may or may not have been independently replicated. Effect sizes and sample sizes are not available in the current dataset, limiting assessment of practical magnitude. The most important caveat: trait labels here are categorical ("neurological," "mental_health") rather than specific diagnoses, which limits clinical interpretation.

What this is NOT

These variants represent population-level statistical associations from genomic research - they are not deterministic predictors of disease or health outcomes for any individual. Nothing here constitutes medical advice, a diagnosis, or a recommendation to take any action.
