Genes affected

WDR72 (HGNC:26790): (WD repeat domain 72) This gene encodes a protein with eight WD-40 repeats. Mutations in this gene have been associated with amelogenesis imperfecta hypomaturation type 2A3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2013]

LOC105370826 (HGNC:):
