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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Dec 06, 2022	The c.1220T>C (p.M407T) alteration is located in exon 7 (coding exon 6) of the PRICKLE2 gene. This alteration results from a T to C substitution at nucleotide position 1220, causing the methionine (M) at amino acid position 407 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
