Genes affected

ZNF148 (HGNC:12933): (zinc finger protein 148) The protein encoded by this gene is a member of the Kruppel family of zinc finger DNA binding proteins. The encoded protein activates transcription of the T-cell receptor and intestinal alkaline phosphatase genes but represses transcription of the ornithine decarboxylase, vimentin, gastrin, stomelysin, and enolase genes. Increased expression of this gene results in decreased patient survival rates from colorectal cancer, while mutations in this gene have been associated with global developmental delay, hypoplastic corpus callosum, and dysmorphic facies.

ZNF148 Gene-Disease associations (from GenCC):

• global developmental delay, absent or hypoplastic corpus callosum, and dysmorphic facies

  Inheritance: AD Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)
