Amelogenesis Imperfecta Hypomaturation Type IIA5

Amelogenesis Imperfecta Type 2


  • Brown pigment is present in middle layers of enamel. Disease Ontology : 12 An amelogenesis imperfecta that has material basis in homozygous mutation in the SLC24A4 gene on chromosome 14q32.[malacards.org]
  • Brown pigment is present in middle layers of enamel. {ECO:0000269 PubMed:23375655, ECO:0000269 PubMed:24621671}. Note The disease is caused by mutations affecting the gene represented in this entry.[genecards.org]
  • Females that have an altered gene present on one of their X chromosomes are carriers for that disorder. Carrier females usually do not display symptoms because females have two X chromosomes and only one carries the altered gene.[rarediseases.org]
