Genes affected

CASZ1 (HGNC:26002): (castor zinc finger 1) The protein encoded by this gene is a zinc finger transcription factor. The encoded protein may function as a tumor suppressor, and single nucleotide polymorphisms in this gene are associated with blood pressure variation. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Jul 2012]

CASZ1 Gene-Disease associations (from GenCC):

• congenital heart disease
