Amelogenesis imperfecta 1J (AI1J)1 Publication
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionA form of amelogenesis imperfecta, a disorder characterized by defective enamel formation. The enamel may be hypoplastic, hypomineralized or both, and affected teeth may be discoloured, sensitive or prone to disintegration. AI1J is an autosomal recessive form characterized by hypoplastic enamel, enamel discolorization ranging from yellow to black, and normal dentin.
