Amelogenesis imperfecta type 2A1

Synonyms
AMELOGENESIS IMPERFECTA, PIGMENTED HYPOMATURATION TYPE, 1; Amelogenesis imperfecta, hypomaturation type, IIA1; Amelogenesis imperfecta, type IIA1

Summary

Autosomal recessive amelogenesis imperfecta pigmented hypomaturation type is characterized by enamel of normal thickness that is hypomineralized and has a mottled appearance. The slightly soft enamel detaches easily from the dentin, and radiographs show a lack of contrast between enamel and dentin (Witkop, 1989). Genetic Heterogeneity of the Hypomaturation Type of Amelogenesis Imperfecta See also AI2A2 (612529), caused by mutation in the MMP20 gene (604629); AI2A3 (613211), caused by mutation in the WDR72 gene (613214); and AI2A4 (614832), caused by mutation in the C4ORF26 gene (614829).
