Introduction Oculodentodigital dysplasia (ODDD) is an autosomal dominant syndrome that presents with craniofacial and limb dysmorphisms caused by mutations in the GJA1 gene, which codes for connexin 43 (Cx43), a gap junction protein important in cell-to-cell communication. We present for the first time a family with ODDD, progressive cardiac conduction system disease, and dilated cardiomyopathy.
