Summaries for Amelogenesis Imperfecta, Type Ia

UniProtKB/Swiss-Prot : 73 Amelogenesis imperfecta 1A: A 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.

MalaCards based summary : Amelogenesis Imperfecta, Type Ia, also known as ai1a, is related to culler-jones syndrome and nephrolithiasis/osteoporosis, hypophosphatemic, 2. An important gene associated with Amelogenesis Imperfecta, Type Ia is LAMB3 (Laminin Subunit Beta 3). Affiliated tissues include salivary gland, skin and lung, and related phenotypes are taurodontia and amelogenesis imperfecta

Disease Ontology : 12 An amelogenesis imperfecta that has material basis in heterozygous mutation in the beta-3 laminin gene (LAMB3) on chromosome 1q32.

OMIM : 56 Hypoplastic amelogenesis imperfecta IA is characterized by enamel that may not develop to normal thickness. The enamel may have pits on the labial or buccal surfaces that are often arranged in rows and columns (see Witkop, 1989). (104530)
