{Reference Type}: Case Reports {Title}: New observation of severe tooth malformation in a female patient with ectodermal dysplasia due to the EDA splice acceptor variant c.742-2A>G. {Author}: Reinhold V;Syrjänen S;Kankuri-Tammilehto M; {Journal}: Mol Genet Genomic Med {Volume}: 11 {Issue}: 12 {Year}: 2023 Dec 4 {Factor}: 2.473 {DOI}: 10.1002/mgg3.2275 {Abstract}: BACKGROUND: Ectodermal dysplasias are inherited disorders, which are characterized by congenital defects in two or more ectodermal structures such as skin, sweat glands, hair, nails, teeth, and mucous membranes.
METHODS: Here, we describe a new observation of significant oligodontia in a female patient with the EDA gene variant c.742-2A>G.
RESULTS: The results strongly suggest that the EDA gene variant c.742-2A>G is pathogenic. The oligodontia in the proband was exceptionally severe.
CONCLUSIONS: We demonstrate that the very rare splice acceptor variant EDA c.742-2A>G is associated with severe oligodontia even in females. Our study points that this variant is pathogenic. An early identification of this variant is crucial for planning adequate treatment and follow-up in time by a multidisciplinary team.
