While the GWAS finding of CDHR3 variant rs114947103 as a protective factor against OM has not been replicated (Pickrell et al., 2016), the downregulation of CDHR3 in cholesteatoma compared to mucosal middle ear tissue (adj-p = 0.004) in our RNA-Seq study strongly supports a role for CDHR3 in OM. The gene discussed is CDHR3; the disease is ocular melanoma.
