rs117780285 (CANT1): Adolescent Pain and Anxiety
Key takeaways
- A genome-wide study linked this CANT1 locus to both adolescent pain problems and anxiety, suggesting the two conditions share molecular roots
- Associations are suggestive only (p < 0.00001), not genome-wide significant, so the evidence is preliminary
- A muscle fiber formation pathway was found enriched for both pain and anxiety and replicated across two independent cohorts
- The study used modest sample sizes and authors explicitly caution that statistical power was limited
- No lifestyle or clinical interventions are on record for this variant

What the research says An exploratory joint genome-wide association and pathway analysis of two independent Canadian adolescent cohorts found multiple suggestive genetic associations (p < 0.00001) for both pain problems and anxiety symptoms, with several enriched genetic pathways passing FDR (false discovery rate, a statistical correction that limits the share of false positives among significant results) correction. A pathway regulating myotube differentiation (GO:0010830, the biological process controlling how cells fuse to form muscle fibers) was specifically replicated in association with both traits across both cohorts, pointing to possible shared molecular mechanisms for these two conditions. The study authors characterize the findings as "initial support" and note they are limited by sample size and statistical power.
Reported associations
- Adolescent pain problems: Suggestive genetic association (p < 0.00001) in the Quebec Newborn Twin Study (QNTS), with participants assessed at ages 12, 13, and 14; genetic analyses included 246 twin pairs and 321 parents
- Adolescent anxiety symptoms: Suggestive association (p < 0.00001) in the same QNTS cohort; many enriched pathways overlapped with those found for the pain phenotype
- Pain-anxiety shared pathways: The myotube differentiation pathway (GO:0010830) showed replicated association with both traits across the QNTS and the independent Longitudinal Study of Child Development in Quebec (QLSCD; n = 754)
Evidence quality Evidence for this variant is preliminary and exploratory. The primary discovery cohort (QNTS) included 246 twin pairs and 321 parents for genetic analysis; the replication cohort (QLSCD) included 754 participants. Associations at the suggestive threshold (p < 0.00001) fall short of the conventional genome-wide significance level (p < 0.00000005), a roughly 200-fold stricter standard, meaning a higher rate of false positive findings is expected at this threshold. The study authors themselves state the work is "limited by sample size and thus power" and describe results as providing "initial support" rather than confirmed associations. Pathway-level findings for the myotube differentiation pathway were replicated across both cohorts, but individual variant-level replication is not described in the provided study text. No conflicting studies are available in the provided evidence base.

Frequently asked questions
What is rs117780285 associated with?
rs117780285, near the CANT1 gene, showed suggestive associations with both pain problems and anxiety symptoms in Canadian adolescents in an exploratory genome-wide study. These associations did not reach the conventional genome-wide significance level, and the evidence is considered preliminary.
Is rs117780285 linked to chronic pain?
This variant was identified at a suggestive statistical threshold (p < 0.00001) in a genome-wide study of adolescent pain problems. The finding has not been confirmed at genome-wide significance levels, and the study authors note that limited sample sizes constrained statistical power.
Do pain and anxiety share genetic factors?
The study found overlapping enriched genetic pathways for both adolescent pain and anxiety, including the myotube differentiation pathway, which was replicated across two independent cohorts. This supports the idea of shared genetic mechanisms, though the evidence remains exploratory.
What is the CANT1 gene?
The study provided does not describe the direct biological function of CANT1. The gene appears in the context of a pathway-based genome-wide analysis examining shared genetic factors for pain and anxiety in adolescents.
How reliable is the evidence for this variant?
The evidence is preliminary. Associations were detected at a suggestive statistical threshold in modest-sized cohorts, which the authors themselves describe as limited by sample size and power. Pathway-level, but not individual variant-level, replication was reported across two cohorts.
