Genes affected

RERE (HGNC:9965): (arginine-glutamic acid dipeptide repeats) This gene encodes a member of the atrophin family of arginine-glutamic acid (RE) dipeptide repeat-containing proteins. The encoded protein co-localizes with a transcription factor in the nucleus, and its overexpression triggers apoptosis. A similar protein in mouse associates with histone deacetylase and is thought to function as a transcriptional co-repressor during embryonic development. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

RERE Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder with or without congenital anomalies

  Inheritance: AD Classification: DEFINITIVE Submitted by: ClinGen
• neurodevelopmental disorder with or without anomalies of the brain, eye, or heart
