Genes affected

PRICKLE2 (HGNC:20340): (prickle planar cell polarity protein 2) This gene encodes a homolog of Drosophila prickle. The exact function of this gene is not known, however, studies in mice suggest that it may be involved in seizure prevention. Mutations in this gene are associated with progressive myoclonic epilepsy type 5. [provided by RefSeq, Dec 2011]

PRICKLE2 Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder

  Inheritance: AD Classification: LIMITED Submitted by: ClinGen
• neurodevelopmental disorder

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics
