A novel GJA1 missense mutation in a Polish child with oculodentodigital dysplasia

J Appl Genet. 2009;50(3):297-9. doi: 10.1007/BF03195687.

Abstract

Oculodentodigital dysplasia (ODDD) (OMIM #164200) is a rare congenital, autosomal dominant disorder comprising craniofacial, ocular, dental, and digital anomalies. The syndrome is caused by GJA1 mutations. The clinical phenotype of ODDD involves a characteristic dysmorphic facies, ocular findings (microphthalmia, microcornea, glaucoma), syndactyly type III of the hands, phalangeal abnormalities, diffuse skeletal dysplasia, enamel dysplasia, and hypotrichosis. In a Polish child with the clinical symptoms typical of ODDD, we demonstrated a novel missense mutation c.C31A resulting in p.L11F substitution. Our report provides evidence on the importance of this highly conserved amino acid residue for the proper functioning of GJA1 protein.
