Pewarisan perpaut-x pada amelogenesis imperfecta
A melogenesis lmperfecta adalah kondisi herediter yang mempengaruhi enamel gigi baik gigi sulung maupun permanen. Amelogenesis lmperfecta terbagi lagiI menjadi dua jenis yaitu bentuk Hypoplastic dan bentuk Hypomaturation. Amelogenesis lfll)erfecta terjadi karena mutasi gen selama proses Amelogenesis, dimana mutasi terjadi pada tangan pendek kromosom X (Xp 22.1 - Xp 22.3) yang ditunjuk AIH1. AIH1 mengandung gen protein enamel gigi manusia, Amelogenin (AMGX). Gambaran gangguan enamel adalah: enamel berlubang, tipis, belang-belang, diikuti dentin terbuka. Gangguan enamel diwariskan melalui kromosom seks terutama kromosom X.
A melogenesis lmperfecta is a hereditary condition affecting dental enamel of both primary and permanent dentition. Amelogenesis lmperfecta subdividedI into two types that are Hypoplastic form and Hypomaturation form. Amelogenesis lfll)erfecta happened because of gene mutation during the process of Amelogenesis, where the mutation happened in the short hand of X chromosome (Xp 22.1 - Xp 22.3) designated AIH1. AIH1 contain the human tooth enamel protein gene, Amelogenin (AMGX). Description of enamel disorder are: pitted, thin enamel, mottled, followed with an opened dentin. Enamel disorder is inherited through sex chromosome especially XÂ chromosome.
