Amelogenesis Imperfecta, Hypoplastic/hypomaturation, X-Linked 2

For a description of hypoplastic/hypomaturation amelogenesis imperfecta, see 301200.

Mapping

See 301200 for description of findings in a family suggesting that one form of amelogenesis imperfecta is determined by a mutation in a gene in the Xq22-q28 region (Aldred et al., 1992). This gene may be another reflection of homeology of portions of the 2 arms of the X chromosome resulting from an ancient duplication.
