Genes affected

ZNF644 (HGNC:29222): (zinc finger protein 644) The protein encoded by this gene is a zinc finger transcription factor that may play a role in eye development. Defects in this gene have been associated with high myopia. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

ZNF644 Gene-Disease associations (from GenCC):

myopia 21, autosomal dominant
