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]

Progressive myoclonic epilepsy type 5 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 07, 2018In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with PRICKLE2-related disease. This variant is present in population databases (rs777124617, ExAC 0.01%). This sequence change replaces glutamic acid with lysine at codon 510 of the PRICKLE2 protein (p.Glu510Lys). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and lysine. -
