Summaries for Amelogenesis Imperfecta, Type Ig

About this section
OMIM : 58 Amelogenesis imperfecta type IG, also known as enamel-renal syndrome, is characterized by hypoplastic enamel on primary and secondary dentition, pulp stones, delayed or failed eruption of secondary dentition, gingival overgrowth, and nephrocalcinosis. Blood chemistry analyses are typically normal, and nephrocalcinosis, which is found on renal ultrasound, may not appear until later in life (summary by Wang et al., 2013). (204690)

MalaCards based summary : Amelogenesis Imperfecta, Type Ig, also known as enamel-renal syndrome, is related to robinow syndrome and fibromatosis, gingival, 1, and has symptoms including polyuria An important gene associated with Amelogenesis Imperfecta, Type Ig is FAM20A (FAM20A Golgi Associated Secretory Pathway Pseudokinase). Affiliated tissues include heart, and related phenotypes are gingival overgrowth and nephropathy

Disease Ontology : 12 An amelogenesis imperfecta that has material basis in homozygous or compound heterozygous mutation in the FAM20A gene on chromosome 17q24.

UniProtKB/Swiss-Prot : 76 Amelogenesis imperfecta 1G: A disorder characterized by dental anomalies, gingival overgrowth, and nephrocalcinosis. Dental anomalies include hypoplastic amelogenesis imperfecta, intrapulpal calcifications, delay of tooth eruption, hypodontia/oligodontia, pericoronal radiolucencies and unerupted teeth.
