Any amelogenesis imperfecta in which the cause of the disease is a mutation in the AMELX gene.
Features include always present findings: Anterior open-bite malocclusion. 4 total HPO annotations.
AMELX encodes amelogenin X-linked (191 aa). Plays a role in biomineralization. Seems to regulate the formation of crystallites during the secretory stage of tooth enamel development. Highest expression in Testis (0.4 TPM) and Brain Amygdala (0.1 TPM).
Amelogenesis imperfecta type 1E is associated with mutations in the AMELX gene on chromosome X.
AMELX is classified as a druggable target (Cell Surface, Druggable Genome, and Growth Factor categories) with score 1.3.
Genetic testing for AMELX is available. Testing is considered confirmatory for diagnosis.
Biomarker and diagnostic research for amelogenesis imperfecta type 1E has been reported in the published literature.
Phenotype severity distribution: 1 always present feature.
No clinical trials have been registered for amelogenesis imperfecta type 1E.
14 publications have been identified in PubMed for amelogenesis imperfecta type 1E. Research spans Basic Science / Preclinical (71%), Case Report / Case Series (21%), and Diagnostic / Biomarker (7%).
