Abstract
Oculo-dento-digital dysplasia (ODDD) is a rare autosomal dominant congenital disorder mainly affecting the development of the face, eyes, skeletal system, heart and dentition. ODDD has been mapped to chromosome 6q22-q24 and germline mutations have been identified in the connexin 43 gene, GJA1. Abnormalities of the skin, hair, and nails have been recognized in ODDD but are often easily overlooked. We report an ODDD patient with curly hair, early trichorrhexis nodosa and discrete keratoderma. Molecular genetic studies revealed a novel GJA1 mutation affecting the amino terminus of the gap junction protein alpha-1 (Cx43). In the light of the cutaneous findings in our patient and based on recent ectodermal dysplasia classification systems, we propose to include ODDD in the group of ectodermal dysplasias.
