What the research says A genome-wide association study found rs11127876 in CADM2 associated with early-onset bipolar I disorder (p=5.19×10-8). [PMID 34016946]. GTEx data show the variant increases CADM2 expression in brain, muscle and adipose tissue. GTEx Portal.

Reported associations

  • Early-onset bipolar I disorder: the variant increases risk with a reported effect size of 5.19×10-8, p=0.0354 in replication cohort [PMID 34016946].

Evidence quality The study used 1779 patients and 1060 controls in discovery followed by independent replication with 473 early-onset and 620 non-early-onset participants. The meta-analysis gave a p=5.19×10-8 indicating strong association. No conflicting results were reported. [PMID 34016946].

Tissue-specific expression effects

  • CADM2: increased expression whole blood, aorta, and thyroid GTEx Portal.

What does rs11127876 mean?

It is a DNA change in the CADM2 gene that has been linked to early-onset bipolar I disorder.

Does this affect how much CADM2 is made?

GTEx data show the variant increases CADM2 expression in brain, muscle and fat tissue.

Is this a common variant?

The study found it rare with a p-value of 5.19×10-8 indicating strong association but not necessarily high frequency.
