Genes affected
PRICKLE1 (HGNC:17019): (prickle planar cell polarity protein 1) This gene encodes a nuclear receptor that may be a negative regulator of the Wnt/beta-catenin signaling pathway. The encoded protein localizes to the nuclear membrane and has been implicated in the nuclear trafficking of the transcription repressors REST/NRSF and REST4. Mutations in this gene have been linked to progressive myoclonus epilepsy. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 3.

Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 408 of the PRICKLE1 protein (p.Trp408Arg). This variant is present in population databases (rs376384105, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with PRICKLE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 206666). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt PRICKLE1 protein function with a negative predictive value of 80%. In 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. -

Collection Method: clinical testing

p.Trp408Arg (TGG>CGG): c.1222 T>C in exon 7 of the PRICKLE1 gene (NM_153026.2). The Trp408Arg missense change has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The amino acid substitution is non-conservative as an uncharged, non-polar Tryptophan amino acid residue is replaced by a positively charged, polar Arginine residue. Several in-silico algorithms predict Trp408Arg may be damaging to the structure/function of the protein. However, it alters a position that is not well conserved and to our knowledge, other missense mutations have not been previously reported in this region of the protein. Therefore, based on the currently available information, it is unclear whether Trp408Arg is a disease-causing mutation or a rare benign variant. The variant is found in EPILEPSY panel(s). -
